-# Function
-## 1. 함수
-
-### 함수 선언문
-```javascript
-    function add1(x , y) {
-        return x + y;
-    }
-```
-
-### 함수 선언식 
-```javascript
-    var add2 = function(x, y) {
-        return x + y;
-    }
-```
-

-    // (매개) => (리턴)
-    const add4 = ( x, y) => x + y;
-```
-
-### this
-why doesn't desploy function today?
-
-**Because this keyword!!!!**
-
-function 내부의 this는 외부의 this와 다르기 때문에!!!!
-
-this를 that에 저장해서 써야 했다.
-
-```javascript
-    var relationship1  = {
-        name: 'zero', 
-        friends : ['nero', 'hero', 'xero'],
-        logFrieds: function() {
-            var that = this; // relationship1을 가리키는 this를 that에 저장
-            this.friends.forEach(function(friend) {
-                console.log(that.name, friend);
-            });
-        },
-    };
-    relationship1.logFrieds();
-```
-
-## 2. Arrow Function
-**축약의 장점**
-```javascript
-    // 콜백 함수 -> 나중에 실행되는 함수
-    setTimeout(function() {
-        console.log("settimout");
-    }, 1000);
-
-    // 축약 표현  
-    setTimeout( () => {
-        console.log("setTimeout arrow");
-    } , 1000);
-
-    // callback 함수의 문제가 함수의 인자가 너무 길어...
-    let newArr = [1, 2, 3, 4, 5].map(function(value , index, object) {
-        return value * 2;
-    });
-
-    console.log(newArr);
-
-    // 더 축약 
-    // return도 생략
-    // brace를 가급적 해주는게 좋다 
-    let newArr = [1, 2, 3, 4, 5].map( (v) => (v * 2) );
-    console.log("arrow newArr", newArr);
-```
-
-## 3. Arrow function의 this context
-**화살표 함수는 함수 내부의 this를 외부 this와 같게 만들어 준다.**
-
-원래 foreach function안에 this가 window로 가리켰지만,
-
-relationsthip2를 가리킬 수 있다.
-
-따라서 바깥 스코프인 logFriends()의 this를 그대로 사용할 수 있다.
-
-**상위 스코프의 this를 그대로 물려 받는다.**
-```javascript
-    var relationship2  = {
-        name: 'zero', 
-        friends : ['nero', 'hero', 'xero'],
-        logFrieds() {
-            this.friends.forEach((friend) => {
-                console.log(this.name, friend);
-            });
-        },
-    };
-    relationship2.logFriends();
-```
-
-### 2-1. bind
-__context(this) 문제로 `bind를 많이 사용하고 있다.`__
-
-**this** Object는 function이 아니다. => keyword
-
-this -> window는 printData()를 가지고 있지 않다.
-
-__`보통 함수를 bind로 감싸주면 된다.`__
-
-```javascript
-    const myObj = {
-        runTimeout() {
-            setTimeout(function() {
-                console.log(this === window);
-                // out: true -> bind()를 안 할때
-                // out: false -> bind()를 할 때 
-                
-                this.printData(); 
-                // bind 호출하기 전
-                // this.printData is not a func at 
-                // so bind로 감싸준다.             
-            }.bind(this), 200);
-        }, 
-
-        printData() {
-            console.log("hi yjkwon07!!");
-        }
-    }
-    myObj.runTimeout();
-```
-
-
-### 2-1. Arow Function
-__But, Arrow함수일 경우 다르다.__
-
-this가 가리키는게 window가 아니고 
-
-__this가 가리키는 context가 실행타이밍에 가리키는 것__
-
-```javascript
-    const myObj = {
-        runTimeout() {
-            setTimeout( () => {
-                // out: false!!!
-                console.log(this === window);
-            }, 200);
-        }, 
-
-        printData() {
-            console.log("hi yjkwon07!!");
-        }
-    }
-```
-
-### 2-2. Event_Queue & callback
-**Event_Queue**에 있다가 나중에 실행이 됨 **`this -> window`**
-
-하지만 arrow는 context를 유지하고 있다.
-
-```javascript
-    const el = document.querySelector("p");
-
-    const myObj = {
-
-        register() {
-            el.addEventListener("click", function(event) {
-                // 1. (bind 설정 안할 시)error -> this.printData (not Function)
-                this.printData();
-                // 2. ok
-            }).bind(this);
-        },
-
-        printData() {
-            console.log("clicked!!!");
-        }
-    }
-    myObj.register();
-```
-
-### 2-2. ArrowFunctiob Effect !!!!
-
-__this라는 것이 이전에는 실행 타이밍에 `callback()에` 호출하는곳에서 바뀔수 있지만,__
-
-callback()함수를 감싸고 있는 Object 선언된걸 this가 가리킨다. 
-
-```javascript
-    const myObj = {
-        
-        register() {
-            el.addEventListener("click", (event) => {
-                this.printData(event.target);
-                // ok
-            });
-        },
-
-        printData(el) {
-            console.log("clicked!!!", el.innerText);
-        }
-    }
-
-    el.addEventListener("click", function(event) {
-        // HTMLPargarmentElement -> p 태그를 가리키고 있다.
-        console.log(this);
-    });
-```
-
-## 4. Function default paramaters
-__기본 매개변수__
-
-parameter 부분에서 미리 설정 가능
-```javascript
-    function sum(value , size = {value : 1}) {
-        // size = size || 1;
-        return value * size.value;
-    }
-    console.log(sum(3, 10)); // 30
-    console.log(sum(3, {value : 3})); // 9
-    console.log(sum(3)); // 3
-```
-
-## 5. rest paramaters
-spread operator와 유사
-
-들어오는 인자 값이 number??
-
-### ES3
-가변인자(argument)활용하기 -> 가짜 배열
-
-기본 built-in function인 `arguement가` 있지만
-
-__배열로 사용할 수 없다.__
-
-__`slice` 실행해 줘~~__
-```javascript
-    function checkNum() {
-
-        const argArray = Array.prototype.slice.call(arguments);
-        // Array
-        console.log(toString.call(argArray));
-        // 만약 slice 안하면 Object Arguments 반환
-        
-        // every : 모두가 true일 경우만 true를 반환한다.
-        const result = argArray.every( (v) => typeof v === "number");
-        // false -> "55"는 문자열 
-        console.log(result);
-    }
-
-    const result = checkNum(10, 2, 3, 4,5 , "55");
-```
-
-### ES6 spread operator
-
-매개변수에 ... -> reset parameters
-
-그 이외 변수 값 -> spread operator
-```javascript
-    function checkNum(...argArray) {
-    // Array
-    console.log(toStirng.call(argArray));
-    const result = argArray.every( (v) => typeof v === "number");
-    console.log(result);
-    }
-    const reuslt = checkNum(10 , 2, "55");
-```

-        this.UltraNmae = name,

-        console.log(country, capital);
-    } 
-// age 22
-```
-
-## 2. spread operator, 펼침연산자
-spread(...)를 사용하여 배열의 값들을 복사한다.
-
-__여기서 pre와 newData는 다른(참조 주소가) 데이터이다.__
-
-spread는 **`immutable과정`** 이라는것을 알게된다.
-
-메모리의 새로운 공간에 새로운 데이터를 넣어 참조 한뒤, __완전히 복사__
-
-```javascript
-    let pre = ["apple", "orange", 100];
-    let newData = [...pre];
-
-    console.log(pre, newData);
-    // ["apple", "orange", 100]
-    // ["apple", "orange", 100]
-
-    console.log(pre === newData); // false
-```
-
-## 3. spread operator - 몇가지 활용
-
-### 배열을 특정 위치에 끼워넣을 때 활용
-```javascript
-    let pre = [100, 200, "hello", null];
-    let newData = [0, 1, 2, 3, ...pre, 4];
-    console.log(newData);
-    // [0, 1, 2, 3, 100, 200, "hello", null, 4]
-```
-
-### 매개변수 인자값을 넣을 때 활용
-```javascript
-    function sum(a, b, c) {
-        return a + b + c;
-    }
-    let pre2 = [100 ,200 ,300];
-
-    sum(pre2[0] , pre2[1] , pre2[2]);
-```
-모든 인자를 파라미터 값에 넣어야하는것이 너무 귀찮아.🤔
-
-__1 sol. 이전 방법__
-```javascript
-    function sum(a, b, c) {
-        return a + b + c;
-    }
-    let pre2 = [100 ,200 ,300];
-
-    sum.apply(null, pre2);
-    // out: 600
-```
-
-__2. spread operator__
-```javascript
-    function sum(a, b, c) {
-        return a + b + c;
-    }
-    let pre2 = [100 ,200 ,300];
-
-    sum(...pre2);
-
-    console.log(sum.apply(null, pre2)); // 600
-    console.log("result =>", sum(...pre2)); // 600
-```
-__immutable array__
-
-즉, 배열을 바꾸지 않고 새로운 값을 복사할 수 있는 방법을 제공
-
-배열을 merge하거나 spread하는방법으로 
-
-__배열을 합치거나 펼쳐진 상태로 새로운 인자값으로 전달할 수 있는 기능__
-
-## 4. from 메서드로 인자(arguments) 배열 만들기
-
-### argument

-
-    console.log(bool); // [10, true]
-```
-
-``` javascript
-    const m = (x, y) => console.log(x, y);
-    m(5, 6) // 5 6 
-
-    m(5, 6, 7, 8, 9); // 5 6
-```
-
-```javascript
-    const n = (X, ...y) => console.log(X, y);
-
-    n(5, 6, 7, 8,  9) // 5, (4) [ 6, 7, 8, 9]
-```
-

-        console.log(arguments);
-    }
-    o(1, 2, 3, 4, 5) // [1 2,3,4,5];
-
-    // 더이상 arguement를 사용하지 않는다.
-    const p = (...rest) => console.log(rest);
-    p(5, 6, 7, 8, 9) // [5, 6, 7, ,8 ,9 ]

-# Destructuring
-## 1. Destructuring Array
-
-필요한 배열에 특정 인덱스값이 의미가 있을 때 뽑아서 쓸 수 있다.
-```javascript
-    let data = ["yjkwon07", "honux", "jk", "jinny"];
-
-    let jisu = data[0];
-    let jung = data[2];
-```
-
-변수에 배열이나 Object에 값을 할당할 때 유용함
-```javascript
-    let [jisu, ,jung] = data;
-    console.log(jisu, jung); // out: yjkwon07, honux
-```
-
-## 2. Destructuring Object
-```javascript
-    let obj = {
-        name : "yjkwon07",
-        address : "Korea",
-        age : 10
-    }
-
-    let {name, age} = obj;
-    console.log(name , age); // out: yjkwon07 10
-```
-
-다른 변수 명을 정할 수 있다.
-```javascript
-    let obj = {
-        name : "yjkwon07",
-        address : "Korea",
-        age : 10
-    }
-    
-    let {name : myName , age : myAge} = obj;
-    console.log(myName , myAge);
-```
-
-## 3. Destructuring 활용 JSON파싱
-```javascript
-    var news = [
-        {
-            "title" : "sbs",
-            "image" : "https://",
-            "newslist" : [
-                "[가나다] 가나다",
-                "가나다 [가나다]"
-            ]
-        },
-        {
-            "title" : "mbc",
-            "image" : "https://",
-            "newslist" : [
-                "[라마바사] 라마바사",
-                "라마바사 [라마바사]"
-            ] 
-        }
-    ];
-
-    let [, mbc] = news; 
-    let {title, image} = mbc;
-    console.log(title , image); // out: mbc https://
-```
-
-### 로직 개선
-
-한방에 뽑는 방법 
-
-한줄을 줄여줌 !!! 완전 우아하네 ~~
-
-```javascript
-    let [, {title, image}] = news;
-    console.log(image);
-```
-
-### 또다른 방법
-
-매개변수에서 destructuring
-
-newslist만 출력
-
-```javascript
-    function getNewsList([, {newslist}]) {
-        console.log(newslist);
-    }
-    getNewsList(news);
-```
-
-## 4. Destructuring활용_Event 객체 전달
-
-event객체에서 target만 가져온다.
-
-```javascript
-    document.querySelector("div").addEventListener("click", function (event) {
-        // event -> 오브젝트
-        console.log(event);
-        console.log(event.target.tagName);
-    });
-    document.querySelector("div").addEventListener("click", function ({ target }) {
-        console.log(target.tagName);
-    });
-```
-
-## 5. Destructuring의 문제점
-getCandy로 따로 값을 받아오게 된다면 this의 위치를 못찾아서 값을 undefined로 리턴한다.
-
-arrow func 으로 해도 못 찾는다.
-```javascript
-// 객체 리터럴
-const candyMachine = {
-    status: {
-        name : 'node',
-        count : 5,
-    },
-    getCandy() {
-        this.status.count--;
-        return this.status.count;
-    }
-};
-// const a = 객체.a
-// const b = 객체.b를 
-// const{ a, b } = 객체로 바꿀 수 있다.
-const {status , getCandy} = candyMachine;
-
-// 비구조화 할당 시 this가 의도와 다르게 동작하는 현상이 있을 수 있다.
-candyMachine.getCandy(); // 4
-getCandy(); // undefined 
-```
-
-### call(Solve)
-
-```javascript
-candyMachine.getCandy(); // 3
-getCandy.call(candyMachine); // 2
-getCandy(); // undefined
-```

+### for - in 의 문제점(Array)
+
+- **Object prototype도 순회한다.** __`array도 일종의 Object`__
+
+```javascript
+  var data = [1, 2, undefined, NaN, null, ""];
+  for (var i = 0; i < data.length; i++) {
+      console.log(i);
+  }
+

+      console.log("valueis", vlaue);
+  });
+  
+  // bad............
+  for (let idx in data) {
+      console.log(data[idx]);
+  }
+```
+
+- __자신이 갖고 있지 않은 상위의 값도 포함해서 결과에 출력할 수 있다.__
+
+```javascript
+  var data = [1, 2, undefined, NaN, null, ""];
+  Array.prototype.getIndex = function () { };
+  
+  for (let idx in data) {
+      console.log(data[idx]); // 출력시 function(){} 출력
+  }
+```
+
+### for - of(Solve)
+
+- __`배열 뿐만 아니라 문자열도 iterable이 가능하다`__
+- 문자 단위로 출력 (공백도 포함)
+
+```javascript
+  var data = [1, 2, undefined, NaN, null, ""];
+  Array.prototype.getIndex = function () { };
+  for(let value of data) {
+      console.log(value);
+  }
+  
+  var str = "hello world!!!";
+  for(let value of str) {
+      console.log(value);
+  }
+```
+
+### Object using for - in
+
+- **prototype link의 연결된 prototype Object의 key 까지 출력** 
+
+```javascript
+  function Ultra(name){
+      this.UltraNmae = name, 
+      this.sf = function sf(){console.log("Ultra sf")}
+  }
+  Ultra.prototype.ultraProp = true;

+  
+  for(var ss in obj) console.log(ss);
+```
+
+```
+  age
+  name
+  UltraNmae
+  sf
+  ultraProp
+```
+
+### Object using for - of
+
+**`for keyword is only using the iterable Data`**
+
+- __But, object is not iterable__
+
+```javascript
+  for(var s of obj) console.log(s); // VM3604:1 Uncaught TypeError: os is not iterable
+```
+
+- __So. Object.key()__
+
+```javascript
+  for (let country of Object.keys(obj)) {
+      var capital = obj[country];
+      console.log(country, capital);
+  } 
+  // age 22
+```
+
+## 2. spread operator, 펼침연산자(immutable)
+
+- spread(...)를 사용하여 배열의 값들을 복사한다.
+- __여기서 pre와 newData는 다른(참조 주소가) 데이터이다.__
+- spread는 **`immutable과정`** 이라는것을 알게된다.
+- 메모리의 새로운 공간에 새로운 데이터를 넣어 참조 한뒤, __완전히 복사__
+
+```javascript
+  let pre = ["apple", "orange", 100];
+  let newData = [...pre];
+  
+  console.log(pre, newData);
+  // ["apple", "orange", 100]
+  // ["apple", "orange", 100]
+  
+  console.log(pre === newData); // false
+```
+
+## 3. spread operator - 몇가지 활용
+
+### 배열을 특정 위치에 끼워넣을 때 활용
+
+```javascript
+  let pre = [100, 200, "hello", null];
+  let newData = [0, 1, 2, 3, ...pre, 4];
+  console.log(newData);
+  // [0, 1, 2, 3, 100, 200, "hello", null, 4]
+```
+
+### 매개변수 인자값을 넣을 때 활용
+
+```javascript
+  function sum(a, b, c) {
+      return a + b + c;
+  }
+  
+  let pre2 = [100 ,200 ,300];
+  sum(pre2[0] , pre2[1] , pre2[2]);
+```
+
+- 모든 인자를 파라미터 값에 넣어야하는것이 너무 귀찮아.🤔
+- __1 sol. 이전 방법__
+
+```javascript
+    function sum(a, b, c) {
+        return a + b + c;
+    }
+    let pre2 = [100 ,200 ,300];
+
+    sum.apply(null, pre2);
+    // out: 600
+```
+
+__2. spread operator__
+
+```javascript
+    function sum(a, b, c) {
+        return a + b + c;
+    }
+    let pre2 = [100 ,200 ,300];
+
+    sum(...pre2);
+
+    console.log(sum.apply(null, pre2)); // 600
+    console.log("result =>", sum(...pre2)); // 600
+```
+
+- __immutable array__
+- 즉, 배열을 바꾸지 않고 새로운 값을 복사할 수 있는 방법을 제공
+- 배열을 merge하거나 spread하는방법으로 
+- __배열을 합치거나 펼쳐진 상태로 새로운 인자값으로 전달할 수 있는 기능__
+
+## 4. from 메서드로 인자(arguments) 배열 만들기
+
+### argument
+
+- 인자값을 안주더라도 내부값의 **argument(객체)라는** 펀션(function)안에 있는
+- __내부 지역변수와 같은 특별한 값을 이용한다.__ -> 배열과 비슷한 형태
+- __아주 권장되는 패턴은 아니다.__
+
+```javascript
+  function addMark() {
+    let newData = [];
+    for (let i = 0; i < arguments.length; i++) {
+        newData.push(arguments[i] + "!");
+    }
+    console.log(newData);
+  }
+  addMark(1, 2, 3, 4, 5);
+```
+
+### Error -> arguments는 map을 못쓴다.
+
+- map을 사용하여 순회하면서 필요한 값을 추가하고, 새로운 배열을 반환
+- __But arguments는 map을 못쓴다.. `배열이 아니기 때문에`__
+
+```javascript
+  function addMark() {
+    let newData = arguments.map(function (value) {
+      return value + "!";
+    });
+    console.log(newData);
+  }
+  addMark(1, 2, 3, 4, 5); // Error
+```
+
+### from(Solve)
+
+```javascript
+  function addMark2() {
+    let newArray = Array.from(arguments);
+    let newData = newArray.map(function (value) {
+      return value + "!";
+    });
+    console.log(newData);
+  }
+  addMark2(1, 2, 3, 4, 5);
+```
+
+## 5. 변수 초기화 
+
+- (...변수)는 rest로 여러 개의 변수를 모아서 배열로 만든다.
+
+```javascript
+    const array = ['nodejs', {}, 10, true];
+    const [node, obj, ...bool] = array;
+
+    console.log(bool); // [10, true]
+```
+
+``` javascript
+    const m = (x, y) => console.log(x, y);
+    m(5, 6) // 5 6 
+
+    m(5, 6, 7, 8, 9); // 5 6
+```
+
+```javascript
+    const n = (X, ...y) => console.log(X, y);
+
+    n(5, 6, 7, 8,  9) // 5, [ 6, 7, 8, 9]
+```
+
+```javascript
+  function o() {
+    console.log(arguments);
+  }
+  o(1, 2, 3, 4, 5) // [1 2,3,4,5];
+  
+  // 더이상 arguement를 사용하지 않는다.
+  const p = (...rest) => console.log(rest);
+  p(5, 6, 7, 8, 9) // [5, 6, 7, ,8 ,9 ]
+```

+# Destructuring
+
+## 1. Destructuring Array
+
+- 필요한 배열에 특정 인덱스값이 의미가 있을 때 뽑아서 쓸 수 있다.
+
+```javascript
+  let data = ["yjkwon07", "honux", "jk", "jinny"];  
+  let jisu = data[0];
+  let jung = data[2];
+```
+
+- 변수에 배열이나 Object에 값을 할당할 때 유용함
+
+```javascript
+    let [jisu, ,jung] = data;
+    console.log(jisu, jung); // out: yjkwon07, honux
+```
+
+## 2. Destructuring Object
+
+```javascript
+    let obj = {
+        name : "yjkwon07",
+        address : "Korea",
+        age : 10
+    }
+
+    let {name, age} = obj;
+    console.log(name , age); // out: yjkwon07 10
+```
+
+- 다른 변수 명을 정할 수 있다.
+
+```javascript
+    let obj = {
+        name : "yjkwon07",
+        address : "Korea",
+        age : 10
+    }
+    
+    let {name : myName , age : myAge} = obj;
+    console.log(myName , myAge);
+```
+
+## 3. Destructuring 활용 JSON파싱
+
+```javascript
+  var news = [
+    {
+      "title" : "sbs",
+      "image" : "https://",
+      "newslist" : [
+        "[가나다] 가나다",
+        "가나다 [가나다]"
+      ]
+    },
+    {
+      "title" : "mbc",
+      "image" : "https://",
+      "newslist" : [
+        "[라마바사] 라마바사",
+        "라마바사 [라마바사]"
+      ] 
+    }
+  ];
+  
+  let [, mbc] = news; 
+  let {title, image} = mbc;
+  console.log(title , image); // out: mbc https://
+```
+
+### 로직 개선
+
+- 한방에 뽑는 방법 
+
+```javascript
+  let [, {title, image}] = news;
+  console.log(image);
+```
+
+### 또다른 방법
+
+- 매개변수에서 destructuring
+- newslist만 출력
+
+```javascript
+  function getNewsList([, {newslist}]) {
+    console.log(newslist);
+  }
+  getNewsList(news);
+```
+
+## 4. Destructuring활용_Event 객체 전달
+
+- event객체에서 target만 가져온다.
+
+```javascript
+  document.querySelector("div").addEventListener("click", function (event) {
+    // event -> 오브젝트
+    console.log(event);
+    console.log(event.target.tagName);
+  });
+  document.querySelector("div").addEventListener("click", function ({ target }) {
+    console.log(target.tagName);
+  });
+```
+
+## 5. Destructuring의 문제점
+
+- getCandy로 따로 값을 받아오게 된다면 this의 위치를 못찾아서 값을 undefined로 리턴한다.
+- arrow func 으로 해도 못 찾는다.
+
+```javascript
+  // 객체 리터럴
+  const candyMachine = {
+    status: {
+      name : 'node',
+      count : 5,
+    },
+    getCandy() {
+      this.status.count--;
+      return this.status.count;
+    }
+  };
+
+  // const a = 객체.a
+  // const b = 객체.b를 
+  // const{ a, b } = 객체로 바꿀 수 있다.
+  const {status , getCandy} = candyMachine;
+  
+  // 비구조화 할당 시 this가 의도와 다르게 동작하는 현상이 있을 수 있다.
+  candyMachine.getCandy(); // 4
+  getCandy(); // undefined 
+```
+
+### call(Solve)
+
+```javascript
+  candyMachine.getCandy(); // 3
+  getCandy.call(candyMachine); // 2
+  getCandy(); // undefined
+```

+```
+
+## 3. Arrow function의 this context
+
+- **화살표 함수는 함수 내부의 this를 외부 this와 같게 만들어 준다.**
+- 원래 forEach function안에 this가 window로 가리켰지만, relationsthip2를 가리킬 수 있다.
+- 따라서 바깥 스코프인 logFriends()의 this를 그대로 사용할 수 있다.
+- **상위 스코프의 this를 그대로 물려 받는다.**
+
+```javascript
+  var relationship2  = {
+    name: 'zero', 
+    friends : ['nero', 'hero', 'xero'],
+    logFrieds() {
+      this.friends.forEach((friend) => {
+        console.log(this.name, friend);
+      });
+    }
+  };
+  relationship2.logFriends();
+```
+
+### 3-1. bind
+
+- __context(this) 문제로 `bind를 많이 사용하고 있다.`__
+- **this** Object는 function이 아니다. => keyword
+- this -> window는 printData()를 가지고 있지 않다.
+- __`보통 함수를 bind로 감싸주면 된다.`__
+
+```javascript
+  const myObj = {
+    runTimeout() {
+      setTimeout(function() {
+        console.log(this === window);
+        // out: true -> bind()를 안 할때
+        // out: false -> bind()를 할 때 
+        
+        this.printData(); 
+        // bind 호출하기 전
+        // this.printData is not a func at 
+        // so bind로 감싸준다.             
+      }.bind(this), 200);
+    },
+
+    printData() {
+      console.log("hi yjkwon07!!");
+    }
+  }
+  myObj.runTimeout();
+```
+
+### 3-2. Arow Function
+
+- __But, Arrow함수일 경우 다르다.__
+- this가 가리키는게 window가 아니고 
+- __this가 가리키는 context가 실행타이밍에 가리키는 것__
+
+```javascript
+  const myObj = {
+    runTimeout() {
+      setTimeout(() => {
+        // out: false!!!
+        console.log(this === window);
+      }, 200);
+    },   
+    printData() {
+      console.log("hi yjkwon07!!");
+    }
+  }
+```
+
+### 3-3. Event_Queue & callback
+
+- **Event_Queue**에 있다가 나중에 실행이 됨 **`this -> window`**
+- 하지만 arrow는 context를 유지하고 있다.
+
+```javascript
+  const el = document.querySelector("p");  
+  const myObj = {  
+    register() {
+      el.addEventListener("click", function(event) {
+        // 1. (bind 설정 안할 시)error -> this.printData (not Function)
+        this.printData();
+        // 2. ok
+      }).bind(this);
+    },  
+    printData() {
+      console.log("clicked!!!");
+    }
+  }
+  myObj.register();
+```
+
+### 3-4. ArrowFunctiob Effect !!!!
+
+- __this라는 것이 이전에는 실행 타이밍에 `callback()에` 호출하는곳에서 바뀔수 있지만,__
+- callback()함수를 감싸고 있는 Object 선언된걸 this가 가리킨다. 
+
+```javascript
+  const myObj = {
+    register() {
+        el.addEventListener("click", (event) => {
+          this.printData(event.target);
+          // ok
+        });
+    },  
+    printData(el) {
+      console.log("clicked!!!", el.innerText);
+    }
+  }  
+  el.addEventListener("click", function(event) {
+    // HTMLPargarmentElement -> p 태그를 가리키고 있다.
+    console.log(this);
+  });
+```
+
+## 4. Function default paramaters
+
+- __기본 매개변수__
+- parameter 부분에서 미리 설정 가능
+
+```javascript
+  function sum(value, size = {value : 1}) {
+    // size = size || 1;
+    return value * size.value;
+  }
+  console.log(sum(3, 10)); // 30
+  console.log(sum(3, {value : 3})); // 9
+  console.log(sum(3)); // 3
+```
+
+## 5. rest paramaters
+
+- spread operator와 유사
+- 들어오는 인자 값이 number??
+
+### ES3
+
+- 가변인자(argument)활용하기 -> 유사 배열
+- 기본 built-in function인 `arguement가` 있지만
+- __배열로 사용할 수 없다.__
+- __`slice`__
+
+```javascript
+  function checkNum() {  
+    const argArray = Array.prototype.slice.call(arguments);
+    // Array
+    console.log(toString.call(argArray));
+    // 만약 slice 안하면 Object Arguments 반환
+    
+    // every : 모두가 true일 경우만 true를 반환한다.
+    const result = argArray.every( (v) => typeof v === "number");
+    // false -> "55"는 문자열 
+    console.log(result);
+  }  
+  const result = checkNum(10, 2, 3, 4,5 , "55");
+```
+
+### ES6 spread operator
+
+- 매개변수에 ... -> reset parameters
+- 그 이외 변수 값 -> spread operator
+
+```javascript
+  function checkNum(...argArray) {
+    // Array
+    console.log(toStirng.call(argArray));
+    const result = argArray.every( (v) => typeof v === "number");
+    console.log(result);
+  }
+  const reuslt = checkNum(10 , 2, "55");
+```

+# Map & WeakMap
+
+## 1. Map & WeakMap 추가정보를 담은 객체 저장하기
+
+- 개선해보려고 노력한 STL
+- `Array` -> set, weakSet
+- `Object` -> map, weakMap
+- __map은 key / value__
+
+**WeakMap**
+
+```javascript
+  let wm = new WeakMap();
+  let myfun = function(){};
+  
+  // 이 함수가 얼마나 실행됐지?를 알려고 할 때...? count
+  wm.set(myfun, 0);
+  
+  // out: function => 0 
+  console.log(wm);
+  
+  let count = 0; 
+  for(let i = 0; i < 10; i++) {
+    count = wm.get(myfun); // get value
+    count++;
+    wm.set(myfun, count);
+  }
+  
+  // console.log(wm);
+  // out: 10
+  console.log(wm.get(myfun));
+  
+  // garbageCollector
+  myfun = null; 
+  // out: undefined
+  console.log(wm.get(myfun));
+  // out: false
+  console.log(wm.has(myfun));
+```
+
+## 2. WeakMap 클래스 인스턴스 변수 보호하기 
+
+### 1. 객체 생성
+
+- private variable create
+
+```javascript
+  function Area(height, width){
+    this.height = height;
+    this.width = width;
+  }
+  
+  Area.prototype.getArea = function() {
+    return this.height * this.width;
+  }
+  
+  let myarea = new Area(10, 20);
+  console.log(myarea.getArea());
+  console.log(myarea.height); // 출력이 된다... 
+```
+
+```javascript
+  const obj = {};
+  function Area3(height, width){
+    obj['height'] = height;
+    obj['width'] = width;
+  }
+  Area3.prototype.getArea = function() {
+    return obj.height * obj.width;
+  }
+  let myarea3 = new Area3(10, 20);
+  
+  console.log(obj);
+  // garbageCollector 대상이 아니다.
+  // 계속 쌓여 나감... (Warning)
+  myarea = null;
+  console.log(obj);
+```
+
+### 2. 개선 방향
+
+__wm 장점 부각__
+
+```javascript
+  const wm = new WeakMap();
+  function Area2(height, width){
+    // 단점은 클래스 밖에 전역변수를 보관하고 있다...
+    wm.set(this, {height, width});
+  }
+  Area2.prototype.getArea = function() {
+    const {height, width} = wm.get(this);
+    return height * width;
+  }
+  let myarea2 = new Area2(10, 20);
+  console.log(myarea2.getArea());
+  console.log(myarea2.height); // undefined
+  // 전역변수 -> weakMap 활용 !! 
+  console.log(wm.has(myarea2));
+  // out: true
+  myarea2 = null;

+
+## Compile & RunTime Engine
+
+- 다양한 웹브라우저(Chrome, Edge, ...) 혹은 Node같이 `JS를 실행 시키기 위한(compile & runTime)` 다양한 **엔진을** 지원한다.
+
+  - JS Engine
+    - 자바스크립트 코드를 실행하는 프로그램 혹은 인터프리터를 말한다.(No Compiler)
+    - 표준적인 인터프리터로 구현될 수도 있고 혹은 자바스크립트 코드를 바이트코드로 컴파일하는 JIT(Just-In-Time) 컴파일러로 구현할 수도 있다.
+
+  - V8 Engine
+    - 자바스크립트 대표적인 엔진은 C++로 구현된 V8 엔진을 볼 수 있다.
+    - 속도 향상을 위해 V8은 인터프리터를 사용하는 대신 JS 코드를 더 효율적인 머신 코드로 번역한다. (하지만, **중간코드를 생산하지 않는다.**)
+    - 멀티 스레드로 컴파일 실행(main thread), 컴파일, 프로파일러, GC Sweep 등이 있다.
+
+## V8 Engine
+
+- Stack
+    - 실행 가능한 함수들을(stack Frame) 순차적으로 실행하는 공간
+    - JS는 싱글 쓰레드 프로그래밍 언어
+      - 콜스택이 하 나 
+      - 따라서 한 번에 하나의 일만 할 수 있다.
+- Heap
+  - 동적으로 생성된 인스턴스(객체)를 관리하는 영역
+
+## Single Thread & EventLoop, Queue
+
+- JS는 싱글 스레드이기 때문에 실행 가능한 코드의 지연이 오래 걸릴 수 록 UI Render 문제 혹은 프로그램이 다운이 될 수 있다.
+  - 그래서 대부분 브라우저는 Web API를 구현하여 비동기적 실행을 가능하게 구현이 되어있다.
+  - **V8 Engine의 속해있지 않은 외부에서(브라우저) 구현된 구조이다.**
+
+- Queue
+  - Microtask Queue (1순위 stack 반영) (ex. then(...) func. of promise func. )
+  - Animation frames (2순위 stack 반영) (ex. UI render or repaint)
+  - Task Queue (3순위 stack 반영)
+
+  - Web API에서 실행 완료후 CallBack 함수를 Queue에 push 한다.
+    - 호출된 함수의 특성을 통해 Microtask, Animation, Task를 보낸다.
+
+- EventLoop
+  - EventLoop는 JS Engine의 call Stack이 비어있으면 eventLoop가 queue를 확인하여 call stack에 보낸다.
+  ```js
+    while(queue.waitForMessage()){
+      queue.processNextMessage();
+    }
+  ```
+    - queue.waitForMessage() 함수는 현재 아무 메시지도 없다면 새로운 메시지 도착을 **동기적으로 기다린다.**
+  - EventLoop에 대해 개념을 잡을 수 있는 유명한 영상이 있다. [What the heck is event loop? | Philip Roberts | JSConf EU](https://youtu.be/8aGhZQkoFbQ)
+
+  ![jsRuntime](../image/jsRuntime.png)
+
+## Hidden Class & Inline Cache (V8 Engine)
+
+- 대부분의 JavaScript 인터프리터가 딕셔너리와 유사한 구조(해쉬함수 기반)를 이용해 **객체 속성 값의 위치를 메모리에 저장한다.**
+  - 하지만, 이럴경우 객체의 속성 값을 찾는데 비용이 많이 든다. 
+
+- JAVA에서는 모든 객체 속성이 `컴파일 전에` **고정된 객체 레이아웃에 의해 결정되고** **런타임에 동적으로 추가되거나 제거될 수 없다.**
+  - 따라서 속성값(혹은 이들 속성을 가리키는 포인터)은 메모리에 고정된 `오프셋을` 가진 **연속적인 버퍼로 저장될 수 있고** `오프셋의 길이는` **속성 타입에 따라 쉽게 결정될 수 있다.**
+
+- V8 Engine의 `Hidden Class는` JAVA와 같은 언어에서 사용되는 고정 객체 레이아웃과 유사하게 작동하는데 **다만 `런타임에` 생성된다는 차이점이 있다.**
+  - 객체가 생성될 때 하나의 `Hidden Class가` 생성되고 프로퍼티 값을 부여 될 때 마다 해당 프로퍼티의 `오프셋을 담은 Hidden Class가 생성되어` 객체가 가리키는 Hidden Class 포인터를 업데이트 한다.
+  - 이전 Hidden Class에는 새로 업데이트한 Hidden Class를 연결한다.
+  - 마지막으로 업데이트한 Hidden Class에는 연결된 Hidden Class를 통해 offset 정보를 쉽게 찾을 수 있다. 
+  - 하지만, 히든클래스 전환은 프로퍼티가 객체에 추가되는 순서에 의존적이다.
+    - 프로퍼티 할당 순서를 바꾸게 된다면 다른 Hidden Class를 생성하므로 최적화 코드가 다르게 된다.
+    - 여기서 `Inline Cache는` 함수에 부여된 파라미터의 객체 참조 Hidden Class 정보를 기억하는데 만약 같은 객체의 다른 Hidden Class를 공유하게 된다면 Inline Cache를 할 수 없어 실행 속도는 하나의 히든클래스와 공유한 코드보다 느리게 된다.
+
+
+## Optimised JavaSript Code
+
+1. 객체 속성의 순서
+    - 객체 속성을 항상 같은 순서로 초기화해서 히든클래스 및 이후에 생성되는 최적화 코드가 공유될 수 있도록 한다.
+  
+2. 동적 속성
+    - 객체 생성 이후에 속성을 추가하는 것은 히든 클래스가 변하도록 강제하고 이전의 히든클래스를 대상으로 최적화되었던 모든 메소드를 느리게 만든다.
+    - 모든 객체의 속성을 생성자에서 할당하는것을 추천한다.
+  
+3. 메소드
+    - 동일한 메소드를 반복적으로 수행하는 코드가 서로 다른 메소드를 한 번씩만 수행하는 코드 보다 더 빠르게 동작한다. (인라인 캐싱 때문)
+
+4. 배열
+     Array 또한 객체로 구성된 배열이다. 즉 메모리에 연속된 주소 참조가 아닐 수 있다. (해시테이블)
+     Array 객체는 희소배열이기 때문에 delete로 프로퍼티를 삭제할 수 있다.
+    - 하지만 프로퍼티를 삭제하지 않는게 좋다.
+    - index 순서가 일정하지 않은 배열은 접근하기에 많은 비용이 든다.
+     또한 커다란 배열을 미리 할당하지 않도록 한다.
+    - 사용하면서 크기가 커지도록 하는 게 낫다. 
+
+5. 태깅된 값
+    - V8은 객체와 숫자를 32비트로 표현한다.
+    - 어떤 값이 오브젝트(flag = 1)인지 혹은 정수(flag = 0)인지는 SMI(Small Integer)라는 하나의 비트에 저장하고 이 때문에 31비트가 남는다. 
+    - 따라서 어떤 숫자가 31비트 보다 크면 V8은 이 숫자를 분리해서 더블 타입으로 전환한 다음 이 숫자를 넣을 새로운 객체를 생성한다. 
+    - 이러한 동작은 비용이 높으므로 가능한한 31비트의 숫자를 사용하도록 하는게 좋다.

+## 함수의 정의
+
+```js
+function hello(x, y) {
+  return x * y;
+} // 함수의 정의(함수 선언)
+
+var hello = function (x, y) {
+  return x * y;
+}; // 리터럴(anonymous function) (함수 표현식)
+
+var hello = new Function("x,y", "return x*y"); // Function 생성자(new 연산자)
+
+var hello = (x, y) => x * y; // 화살표 함수
+```
+
+## 함수 선언 vs 함수 표현식
+
+- 함수 선언도 함수의 표현식과 같은 형태로 저장하는 방식이 같다.
+- 함수명과 함수 참조값을 가진 변수명이 일치하므로 함수명으로 호출되는 듯 보이지만 **사실은 변수명으로 호출된 것이다.**
+- 결국 함수 선언도 함수 표현식과 동일하게 **함수 리터럴 방식으로 정의되는 것이다.**
+
+  ```js
+  function hello(x, y) {
+    return x * y;
+  } // 함수의 정의(함수 선언)
+
+  // INNER CORER
+  var hello = function hello(x, y) {
+    return x * y;
+  }; // 함수의 정의(함수 표현식 => 변수 선언)
+  ```
+
+- 함수 표현식에서 함수이름을 정할 수도 있다. 하지만, 해당 함수 이름으로 호출 할 수 없다. **단지 디버깅시 해당 함수를 쉽게 알기 위함.**
+  ```js
+  var hello = function world(x, y) {
+    return x * y;
+  }; // 리터럴(함수 표현식)
+  world(2, 3); // Error
+  ```
+
+### 호이스팅
+
+- ES6의 let, const를 포함하여 모든 선언(var, let, const, function, function\*, class)을 호이스팅(Hoisting)한다.
+- `호이스팅이란` var 선언문이나 function 선언문 등 모든 선언문이 해당 `Scope의 선두로` 옮겨 동작하는 특성을 말한다.
+
+  - 즉, 모든 선언, 할당되기 이전에 참조 가능하다.
+
+- 여기서 `함수 선언으로` 작업할 경우, **함수 호이스팅이 발생된다.**
+
+  - 함수 호이스팅경우 **해당 함수의 객체를 생성하여(VO)** Reference Type으로 해당 **함수 선언에 연결을 한다.**
+  - 함수 호이스팅으로 선언 이전에 함수를 호출 할 수 있다.
+
+  ```js
+  console.log(hello(2, 3)); // 6
+  function hello(x, y) {
+    return x * y;
+  }
+  ```
+
+- 함수 선언의 경우와는 달리 `함수 표현식의 경우` 함수 호이스팅이 아니라 **변수 호이스팅이 발생한다.**
+
+  - 변수 호이스팅경우 선언문의 이름을 **Scope의 선두로 올리고 값을 `undefined로` 부여한다.**
+  - 즉, 함수의 객체가 생성되지 않았기 때문에 **해당 변수를 함수로 보지않는다.**
+
+  ```js
+  var hello = world(5); // Error
+
+  var world = function (x, y) {
+    return x * y;
+  };
+  ```
+
+## Function 인자 가변 길이 인수(Arguments 객체)
+
+- **Arguments** 객체는 프로퍼티로 `length`와 `callee`를 갖고 있다.
+  - 해당 **Function 객체에서는** `arguments 프로퍼티` 부여
+  - **유사 배열 객체**
+  - length: 인수 개수
+  - callee: 현재 실행되고 있는 함수 참조
+- Argumetns 객체는 인수 목록과 연동되어 **arguments 값을 바꾸면 인수도 바뀐다.**
+  ```js
+  (function (x, y) {
+    arguments[0] = 55;
+    console.log(x, y); // 55, 2
+  })(2, 2);
+  ```
+
+## \[\[Prototype\]\] 접근자 \_\_proto\_\_ 프로퍼티
+
+- `모든 객체는` \[\[Prototype\]\]이라는 내부 슬롯이 있다.
+- \[\[Prototype\]\] 내부 슬롯은 **Prototype 객체를 가리킨다.**
+  - 프로토타입 객체란 프로토타입 기반으로 **상속을 구현하기 위해 사용된다.**
+  - 내부 슬롯을 직접 접근을 못하므로 **`__proto__ 접근자 프로퍼티로` 접근을 한다.**
+- 즉, 프로토타입 객체는 다른 객체에 공유 프로퍼티를 제공하는 객체를 말한다.
+- **prototype 프로퍼티는 함수 객체만이 소유하는 프로퍼티이다.** (일반 객체에는 prototype 프로퍼티가 없다.)
+
+  - 만약 new Object()로 할경우 Object는 생성자 함수로 구현되어있기 때문에 Object.\_\_proto\_\_ === Fucntion.prototype 을 가리키게 된다.
+  - Object로 생성된 인스턴스는 Object.prototype을 가리키게 된다.({}.\_\_proto\_\_ === Object.prototype)
+
+  ![prototype](../image/function_object_prototype.png)
+
+- 여기서 `declare function by User(F)`의 \_\_proto\_\_가 아닌 `prototype은` new F를 호출해 새롭게 만든 객체의 [[Prototype]]을 할당해 주기 위함이다.
+
+## prototype 객체 변경
+
+- `prototype`도 **객체이다.**
+- prototype 객체는 **다른 임의의 객체로 변경할 수 있다.** (객체의 상속)
+- 프로토타입 객체를 변경하는 시점에 따라 생성된 인스턴스(객체)의 prototype이 가리키는 참조값이 달라진다.
+
+```js
+function Hello(next) {
+  this.next = next;
+}
+
+var hi = new Hello("World");
+
+// 프로토타입 객체의 변경
+Hello.prototype = { what: "JavaScript" }; // Object로 생성된 객체 Reference 참조
+
+var hey = new Hello("World!!!!");
+
+console.log(hi.what); // undefined
+console.log(hey.what); // 'JavaScript'
+
+console.log(hi.constructor); // Hello(next)
+console.log(hey.constructor); // Object()
+```
+
+- 프로토타입 객체 변경 후, Hello() 생성자 함수의 Prototype 프로퍼티가 가리키는 프로토타입 객체를 Object 객체로 변경하면서 Hello.prototype.constructor 프로퍼티도 삭제되었다.
+- hey.constructor의 값은 프로토타입 체이닝에 의해 Object 생성자 함수가 된다.
+
+## prototype에 프로퍼티 할당과 호출
+
+```js
+let hamster = {
+  stomach: [],
+
+  eat(food) {
+    this.stomach.push(food);
+  },
+};
+
+let speedy = {
+  __proto__: hamster,
+};
+
+let lazy = {
+  __proto__: hamster,
+};
+```
+
+- 상속된 prototype의 함수를 호출할 때, 함수안에 this.[key] 에따라 상속 받은 객체와 부모 객체 상태가 달라진다.
+
+  - this.[key] : 프로퍼티 할당
+  - this.[key][function] : 함수 호출
+
+- 이 때는 `this.stomach.push`를 `호출했기` 때문에 hamster 객체에 `stomach가` 푸쉬된다.
+- `this.stomach`로 교체한다면 상속하고 있는 객체 `할당된다`.
+
+## 실행 컨텍스트(Excution Context)
+
+- 실행 가능한 코드(Executable Code)를 만나면 그 코드를 평가(Evaluation)하여 실행 문맥(EC)을 만든다.
+
+  - **전역 코드**
+  - **함수 코드**
+  - eval 코드
+    - eval 코드는 lexical Environment가 아닌 동적 환경에 실행 된다.
+
+- JS 엔진은 코드를 실행하기 위해 실행에 필요한 정보들을 알고 있어야 한다.
+  - **변수** (전역변수, 지역변수, 매개변수, 객체의 프로퍼티)
+  - **함수 선언**
+  - **변수의 유효범위(Scope)**
+  - **this**
+
+### 실행 컨텍스트(EC) 프로퍼티
+
+- ![EC](./../image/EC.png)
+
+- Variable Object(VO)
+
+  - value, parameter, arguments, 함수 선언
+  - `실행 컨텍스트에 따라` **가리키는 객체가 달라진다.**
+
+    - `Global Enviroment Context`
+
+      - 전역 코드 즉, 매개변수가 없는 전역코드를 평가하는 시점에서, VO는 전역객체(Global Object /GO)를 가리킨다.
+      - 초기 상태의 전역객체는 빌트인 객체와 BOM, DOM이 구현이되어 있다. (구현이 된 후 전역 실행 컨텍스트가 생성)
+      - 전역 객체는 전역에 선언된 전역 변수와 전역 함수를 프로퍼티로 소유한다.
+
+    - `Funciton Context`
+      - VO는 활성 객체(Activation Object /AO)를 가리키며 매개변수와 인수들의 정보를 배열의 형태로 담고 있는 객체인 arguments object가 추가 된다.
+
+- Scope
+  - 스코프는 `식별자를 검색하는 매커니즘이다.`
+  - [Variable Object + All parent(VO)]
+    - 리스트 형식으로 현재 실행 컨텍스트의 활성 객체를 선두로 시작하여 상위 컨텍스트의 활성 객체를 가리키며 마지막으로 GO를 가리킨다.
+  - 함수 프로퍼티인 `[[Scope]]`로 참조한다.
+- this
+  - context object : 함수를 실행시킨 객체, 전역 코드는 window(브라우저)로 부여한다.
+
+### 실행 컨텍스트 실행(처리) 순서
+
+1. 스코프 체인의 생성과 초기화
+2. Variable Instantiation(변수 객체화) 실행
+
+   - Variable Instantiation은 Variable Object에 프로퍼티와 값을 추가하는 것을 의미한다.
+
+   - 프로퍼티 값 설정 순서
+
+     1. (`Function Code인 경우)` `매개변수(parameter)가` Variable Object의 프로퍼티 `name`으로, `인수(argument)가` `value`로 설정된다.
+     2. 대상 코드 내의 `함수 선언`(함수 표현식 제외)을 대상으로 `함수명이` Variable Object의 `name`으로, 생성된 `함수 객체가` `value`로 설정된다. **(함수 호이스팅)**
+     3. 대상 코드 내의 `변수 선언을` 대상으로` 변수명이` Variable Object의 `name`으로, `undefined가` `value`로 설정된다. (변수 호이스팅)
+
+   - 변수(프로퍼티) 선언 처리
+     1. 선언 단계(Declaration phase)
+        - 변수 객체(Variable Object)에 변수를 등록한다. 이 변수 객체는 스코프가 참조할 수 있는 대상이 된다.
+     2. 초기화 단계(Initialization phase)
+        - 변수 객체(Variable Object)에 등록된 변수를 메모리에 할당한다. 이 단계에서 변수는 `undefined로` 초기화된다.
+     3. 할당 단계(Assignment phase)
+        - `EC가 구성된 후` 전체 코드를 순차적으로 실행될 때 시점이다.
+        - `undefined로` 초기화된 변수에 실제값을 할당한다.
+
+3. this value 결정
+
+### Ex. 실행 가능한 함수 [code]
+
+```js
+var a = "testA";
+
+function outterA() {
+  var b = "testB";
+
+  function nestedB() {
+    var c = "testC";
+    console.log(a, b, c);
+  }
+  nestedB();
+}
+
+outterA();
+```
+
+![EC, GO, AO](./../image/EC_stack.png)
+
+### Ex. 중첩함수 리턴
+
+```js
+function makeCounter() {
+  let count = 0;
+
+  return function () {
+    return count++;
+  };
+}
+
+let counter = makeCounter();
+```
+
+> 모든 함수는 함수가 생성된 곳의 렉시컬 환경을 기억한다는 점입니다.
+> 함수는 [[Environment]]라 불리는 숨김 프로퍼티를 갖는데, 여기에 함수가 만들어진 곳의 렉시컬 환경에 대한 참조가 저장됩니다.
+
+> counter.[[Environment]]엔 {count: 0}이 있는 렉시컬 환경에 대한 참조가 저장됩니다.
+> **호출 장소와 상관없이 함수가 자신이 태어난 곳을 기억할 수 있는 건 바로** [[Environment]] 프로퍼티 덕분입니다.
+>
+> [[Environment]]는 함수가 생성될 때 딱 한 번 그 값이 세팅됩니다. 그리고 이 값은 영원히 변하지 않습니다.
+>
+> counter()를 호출하면 각 호출마다 새로운 렉시컬 환경이 만들어집니다.
+>
+> 그리고 이 렉시컬 환경은 counter.[[Environment]]에 저장된 렉시컬 환경을 외부 렉시컬 환경으로서 참조하게 됩니다.
+
+> new Function을 이용해 만든 함수의 [[Environment]]는 외부 렉시컬 환경이 아닌 전역 렉시컬 환경을 참조하므로 외부 변수를 사용할 수 없습니다.
+>
+> 단점 같아 보이는 특징이긴 하지만 에러를 예방해 준다는 관점에선 장점이 되기도 합니다.
+>
+> 구조상으론 매개변수를 사용해 값을 받는 게 더 낫습니다. 압축기에 의한 에러도 방지할 수 있죠.
+
+## 함수 프로토타입 함수추가 (데코레이터)
+
+- `데코레이터는` 함수를 감싸는 래퍼로 함수의 행동을 변화시킨다.
+- 주요 작업은 여전히 함수에서 처리한다.
+
+```js
+Function.prototype.defer = function (ms) {
+  let f = this; // 호출한 인스턴스 함수 // ex. sayHi (함수도 Function객체의 인스턴스 이다.)
+  return function (...args) {
+    setTimeout(() => f.apply(this, args), ms);
+  };
+};
+
+let user = {
+  name: "John",
+  sayHi() {
+    alert(this.name);
+  },
+};
+
+user.sayHi = user.sayHi.defer(1000);

+
+  - 화살표 함수 표현(arrow function expression)은 function 표현에 비해 구문이 짧고 자신의 `this`, `arguments`, `super`, `prototype`, `yield` 또는 `new.target`을 **바인딩 하지 않는다.**
+  - 화살표 함수는 **항상 익명이다.** 이 함수 표현은 메소드 함수가 아닌 곳에 가장 적합하다. 그래서 **생성자로서 사용할 수 없다.**
+
+> 화살표 함수는 **자신의 this가 없습니다.** 대신 화살표 함수를 둘러싸는 `렉시컬 범위(lexical scope)의 this가 사용됩니다.`
+> 화살표 함수는 일반 변수 조회 규칙(normal variable lookup rules)을 따릅니다. 때문에 **현재 범위에서 존재하지 않는 this를 찾을 때**, 화살표 함수는 `바로 바깥 범위에서` `this를` 찾는것으로 검색을 끝내게 됩니다.

+## Promise 생성
+
+```js
+const p1 = new Promsie((resolve, reject) => {
+  // resolve() // p1 객체는 이행됨(fulfilled)
+  // reject() // p1 객체는 거부됨(rejected)
+  // exception 발생 => 거부됨
+}); // 대기중(pending) 상태 return Promise
+const p2 = Promise.reject(); // return Promise
+const p3 = Promise.resolve(); // reeturn Promise
+```
+
+- new 키워드를 사용해서 프로미스를 생성하는 순간 생성자의 입력함수가 실행
+- 만약 API 용청을 보내는 비동기 코드가 있다면 **프로미스가 생성되는 순간에** 요청을 보낸다.
+
+```js
+const p1 = Promise.resolve(123); // return Promise
+Promise.resolve(p1) === p1; // Promise.resolve 함수에 프로미스가 입력되면 그 자신이 반환된다.
+```
+
+```js
+requestData().then(onResolve, onReject); // 프로미스가 처리됨 상태가 되면 onResolve 함수가 호출 되고, 거부됨 상태가 되면 onRejct 함수가 호출
+Promise.resolve(123).then((data) => console.log(data));
+Promise.reject(123).then(null, (error) => console.log(error));
+```
+
+- 결과적으로 `then` 메서드는 **항상 프로미스를 반환한다.**
+- 프로미스가 `거부됨 상태인` 경우에는 **onReject 함수가 존재하는 then을 만날때까지 이동한다.**
+
+```js
+Promise.reject(data)
+  .then((then1) => console.log("then1", then1))
+  .then((then2) => console.log("then2", then2))
+  .then((then3) => console.log("then3", then3), (then4) => console.log("then4", then4));
+  .then((then5) => console.log("then5", then5), (then6) => console.log("then6", then6));
+```
+
+- 거부된 상태인 프로미스는 처음으로 만나는 onReject 함수를 호출하므로 빈 코드 블록은 생략 된다.
+- onReject 함수는 undefined를 결과로 가지면서 이행됨 상태인 프로미스를 생성한다.
+- 따라서 then5가 출력된다.
+- result: then4 ~ , then5 ~
+
+```js
+Promise.reject(data).catch((error) => console.log("error", error)); // catch 메서드는 then 메서드의 onReject 함수와 같은 역할을 한다.
+Promise.reject(data)
+  .catch((error) => error); // catch 메서드도 새로운 프로미스를 반환한다.
+  .then((then) => console.log("then", then))
+```
+
+```js
+new Promise(function (resolve, reject) {
+  setTimeout(() => {
+    throw new Error("에러 발생!");
+  }, 1000);
+}).catch(alert);
+```
+
+- `.catch는` 트리거 되지 않는다.
+- 암시적 try, .. catch가 함수 코드를 감사고 있으므로 모든 동기적 에러는 암시적 try, ...catch에서 처리 된다.
+- 하지만 여기에서 에러는 excutor(실행자, 실행 함수)가 실행되는 동안이 아니라 나중에 발생한다.
+- **따라서 프로미스는 에러를 처리할 수 없다.**
+- 하지만 `reject로` 호출했을 때는 `catch로` 전달이 된다.
+
+```js
+requestData()
+  .then((data) => {})
+  .catch((error) => {})
+  .finally(() => {});
+```
+
+- finally는 처리됨 상태인 프로미스의 데이터를 건드리지 않고 추가 작업을 할 때 유용하게 쓰인다.
+- requestData 함수의 반환값은 finally 메서드 호출 이전의 프로미스다.
+
+```js
+Promise.all([requestData(), requestData2()]).then(([data1, data2]) => {
+  console.log("data1", data1);
+  console.log("data2", data2);
+}); // return Promise
+```
+
+- `Promise.all` 함수가 반화하는 프로미스는 입력된 **모든 프로미스가 처리됨 상태가** 되어야 처림됨 상태가 된다.
+- 하나라도 거부됨 상태가 된다면 즉시, Promise.all 함수가 반환하는 프로미스도 거부됨 상태가 된다.
+  > fetch를 사용해 호출 여러 개를 만들면, 그중 하나가 실패하더라도 호출은 계속 일어납니다.
+  > 렇더라도 Promise.all은 다른 호출을 더는 신경 쓰지 않습니다. 프라미스가 처리되긴 하겠지만 그 결과는 무시됩니다.
+
+```js
+Promise.race([
+  requestData(),
+  new Promise((_, reject) => setTimeout(reject, 3000)),
+])
+  .then((data) => console.log(data))
+  .catch((error) => console.log(error));
+```
+
+- `Promise.race는` 여러 개의 프로미스 중에서 가장 빨리 처리된 프로미스를 반환하는 함수이다.
+- requestData 함수가 3초 안에 데이터를 받으면 then 메서드가 호출, 그렇지 않으면 catch 메서드 호출
+
+```js
+function requestData(params) {
+  const p = Promise.resolve(10); // 생성되자 마자 실행 => new reslovePromise(10)
+  p.then(() => 20); // then 메서드는 기존 객체를 수정하지 않고, 새로운 프로미스를 반환한다. => new Thenalbe(()=> 20)
+  return p;
+}
+requestData().then((v) => {
+  console.log("v", v); // 10
+});
+```
+
+- 프로미스는 `불변 객체다`.
+
+```js
+function requestData() {
+  return Promise.resolve(10).then((v) => {
+    return 20;
+  });
+}
+requestData().then((v) => {
+  console.log("v", v); // 20
+});
+```
+
+## async await
+
+```js
+async function getData() {
+  return 123;
+} // return Promise
+getData().then((data) => console.log("data", data)); // 123
+```
+
+- `async는` Promise 객체로 변환하여 리턴해주는 키워드이다.
+
+```js
+async function getData() {
+  return Promise.resolve(123); // 프로미스의 then 메서드와 마찬가지로 async await 함수 내부에서 반환하는 값이 프로미스라면 그 객체를 그대로 반환
+}
+getData().then((data) => console.log(data)); // 123
+```
+
+```js
+function requestData(value) {
+  return new Promise((resolve) =>
+    setTimeout(() => {
+      console.log("requestData", value);
+      resolve(value);
+    }, 100)
+  );
+}
+async function getData() {
+  const data1 = await requestData(10); // 프로미스가 처리됨 상태가 될 때까지 다음 코드를 실행하지 않는다. => .then 역할
+  const data2 = await requestData(20);
+  console.log("data1", data1);
+  console.log("data2", data2);
+  return [data1, data2];
+}
+getData(); // Promise
+```
+
+```js
+async function getData() {
+  const p1 = asyncFunc1();
+  const p2 = asyncFunc2();
+  // 두개의 프로미스가 생성되고 각자의 비동기 코드가 실행된다.
+  const data1 = await p1; // await으로 프로미스가 생성된 후 기다리기 때문에 두 개의 비동기 함수가 병렬로 처리된다.
+  const data2 = await p2;
+}
+async function getData() {
+  const [data1, data2] = await Promise.all([asyncFunc1(), asyncFunc2()]);
+}
+```
+
+```js
+class TEX {
+  then(resolve, reject) {
+    setTimeout(() => resolve(1234), 10000);
+  }
+}
+async function asyncFunc() {
+  const result = await new TEX();
+  console.log("result", result); // 1234
+}
+```
+
+- `Thenable은` 프로미스처럼 동작하는 객체다.
+- async await은 ES6의 프로미스가 아니더라도 then 메서드를 가진 객체를 **프로미스처럼 취급한다.**
+- 프로미스가 아니더라도 then 메서드르 가진 객체를 Thenable이라고 부른다.
+
+## 마이크로태스크
+
+- 프로미스 핸들러 `.then/catch/finally는` 항상 비동기적으로 실행된다.
+  > 프라미스가 즉시 이행되더라도 `.then/catch/finally` 아래에 있는 코드는 이 핸들러들이 실행되기 전에 실행됩니다.
+
+```js
+let promise = Promise.resolve();
+
+promise.then(() => console.log("프로미스 성공!"));
+
+console.log("코드 종료"); // 이 로그가 가장 먼저 나타난다.
+```
+
+> 요약하자면, 어떤 프라미스가 준비되었을 때 이 프라미스의 `.then/catch/finally` 핸들러가 마이크로태스크큐에 들어간다고 생각하시면 됩니다.
+>
+> 이때 핸들러들은 여전히 실행되지 않습니다. `현재 코드에서 자유로운 상태가 되었을 때에서야` 자바스크립트 엔진은 큐에서 작업을 꺼내 실행합니다.
+
+> 비동기 작업을 처리하려면 적절한 관리가 필요합니다.
+>
+> 이를 위해 ECMA에선 PromiseJobs라는 내부 큐(internal queue)를 명시합니다.
+>
+> V8 엔진에선 이를 '마이크로태스크 큐(microtask queue)'라고 부르기 때문에 이 용어가 좀 더 선호됩니다.
+
+- JS_Engine 참고
+
+```js
+let promise = Promise.reject(new Error("프로미스 실패!"));
+setTimeout(() => promise.catch((err) => alert("잡았다!")), 1000);
+
+// Error: 프로미스 실패!
+window.addEventListener("unhandledrejection", (event) => alert(event.reason));
+```
+
+- `unhandledrejection은` 마이크로태스크 큐에 있는 작업 모두가 완료되었을 때 생성된다.
+  - `.catch`같이 `에러 헨들러가` 없다면 마이크로태스크 큐는 계속해서 에러 핸들러를 처리하고 요청을 하기 때문에 뒤에있는 테스크가 쌓이게 된다.
+  - 그것을 맞기위해 `unhandlerrejection을` `트리거` 하여 에러를 처리하도록 요청한다.
+- 위 예시를 실행하면 setTimeout을 사용해 추가한 `.catch` 역시 트리거 된다.
+  - 다만 `.catch는` `unhandledrejection이` 발생한 이후에 트리거 되므로 `프로미스 실패!가 출력된다.`

+    const dy = a.y - b.y;
+
+    return Math.hypot(dx, dy);
+  }
+}
+```
+
+- `클래스 필드`
+
+  - 어떤 종류의 프로퍼티도 클래스에 추가할 수 있다.
+  - 생성자.prototype이 아닌 개별 객체에만 클래스 필드가 설정된다.
+  - 즉, 생성자 역할을 다 한 이후에 클래스 필드가 처리된다.
+
+- `method(...) {}` 표현은
+
+  - 메서드는 생성자로 사용할 수 없다. 즉 prototype 프로퍼티를 가지지 않으므로 new 연산자로 인스턴스를 생성할 수 없다.
+  - 객체 표현에서도 동일하다.
+
+## 상속
+
+> 자바스크립트는 `'상속 클래스의 생성자 함수(derived constructor)'와` 그렇지 않은 생성자 함수를 구분합니다.
+> 상속 클래스의 생성자 함수엔 특수 내부 프로퍼티인 `[[ConstructorKind]]:"derived"가` 이름표처럼 붙습니다.
+
+> 일반 클래스가 `new와` 함께 실행되면, 빈 객체가 만들어지고 `this에` 이 객체를 할당합니다.
+> 반면, 상속 클래스의 생성자 함수가 실행되면, 일반 클래스에서 일어난 일이 일어나지 않습니다.
+> 상속 클래스의 생성자 함수는 빈 객체를 만들고 `this에` 이 객체를 할당하는 일을 부모 클래스의 생성자가 처리해주길 기대합니다.
+
+> 이런 차이 때문에 상속 클래스의 생성자에선 `super를` 호출해 부모 생성자를 실행해 주어야 합니다. 그렇지 않으면 `this가` 될 객체가 만들어지지 않아 에러가 발생합니다.
+
+- **클래스 필드 초기화 순서**
+
+  - `아무것도 상속받지 않는 베이스 클래스는` 생성자 실행 이전에 초기화된다.
+  - `부모 클래스가 있는 경우엔` `super()` 실행 직후에 초기화 된다.
+
+- **클래스 생성자의 상속 관계**
+
+  - class B extends A는 `클래스 B의` 프로토타입이(\_\_proto\_\_) `클래스 A를` 가리키게 한다.
+  - (B.[[Prototype]] = A). 따라서 B에서 원하는 프로퍼티나 메서드를 찾지 못하면 A로 검색이 이어진다.
+  - `class` 키워드에서만 이루어지고 `일반 함수의` 생성자 프로토타입 상속은 일반 함수 prototype의 상속관계만 이루어진다. 함수의 생성자의 \_\_proto\_\_은 Function 프로토타입을 가리킨다.
+
+## super 키워드와 \[[HomeObject]\]
+
+- 클래스이거나 객체 메서드인 함수의 \[[HomeObject]] 프로퍼티는 해당 객체가 저장된다.
+- `super는` \[[HomeObject]]를 이용해 부모 프로토타입과 메서드를 찾는다.
+- \[[HomeObject]]는 오직 `super 내부에서만` 유효하다.
+
+> \[[HomeObject]]는 클래스와 일반 객체의 메서드에서 정의됩니다.
+> 그런데 객체 메서드의 경우 \[[HomeObject]]가 제대로 동작하게 하려면 메서드를 반드시 method() 형태로 정의해야 합니다.
+> "method: function()" 형태로 정의하면 안 됩니다.
+
+## instanceof
+
+```js
+class Animal {}
+class Rabbit extends Animal {}
+
+let rabbit = new Rabbit();
+alert(rabbit instanceof Animal); // true
+
+// rabbit.__proto__ === Rabbit.prototype
+// rabbit.__proto__.__proto__ === Animal.prototype (일치!)
+```
+
+> 한편, objA가 objB의 프로토타입 체인 상 어딘가에 있으면 true를 반환해주는 메서드, `objA.isPrototypeOf(objB)도` 있습니다.
+> `obj instanceof Class는` `Class.prototype.isPrototypeOf(obj)와` 동일합니다.
+> 검사 시, 프로토타입 체인과 Class.prototype만 고려합니다.
+> `instanceof는` `평가 시`, 함수는 고려하지 않고 평가 대상의 prototype을 고려합니다.
+> 평가 대상의 prototype이 프로토타입 체인 상에 있는 프로토타입과 일치하는지 여부를 고려하죠.

+## 1. Spec
+
+1. 인터프리터 언어
+
+   - **JIT 컴파일러가** 내장되어 실행속도가 빨라짐
+
+2. 동적 프로토타입 기반 객체 지향 언어
+
+   - JAVA, C++ 에서, 프로그램 실행 중 클래스를 인스턴스화 하여 나온 객체들은 메서드 혹은 상속을 수정할 수 없지만,
+   - JS에서는 `Descriptor에` 따라 `동적으로` 프로토타입, 프로퍼티와 메서드를 **추가, 변경, 삭제 모두 할 수 있다.**
+
+3. 동적 타입 언어
+
+   - **특정 변수 타입이 없다.**
+   - const, let, var
+
+4. 일급 객체 함수
+
+   - **함수(fucntion)도 객체로 지정(Funciton)**
+   - 즉, 값으로 평가한다.
+
+5. 클로저 지원
+   - 내장 함수(Nested Function)를 지원 하여 **하나의 인스턴스화, 은닉이 가능**
+
+## 2. Expressions vs Statement
+
+- 표현식(Expressions)

+  - 문장 여러 개를 `{}`로 감싼 코드를 복합문 또는 블록문이라고 한다.
+  - 문장은 값이 들어와야 할 곳에 들어갈 수 없다. (in JS)
+  - 함수의 인자로도, 대입 연산의 값으로도, 연산자의 피연산자로도 사용될 수 없다.
+  ```js
+    1. if
+    2. if-else
+    3. while
+    4. do-while
+    5. for
+    6. switch
+    7. for-in
+    8. with (deprecated)
+    9. debugger
+    10. variable declaration
+  ```
+
+### 2-1. literal
+
+- 프로그램에서 직접 작성할 수 있는 상수 값은 `리터럴이라고` 한다.
+  - 정수 리터럴 => 123, 0x2a, 0o73, 0b101
+  - 부동소수점 리터럴 => 3.14, 6.02e23
+  - 문자열 리터럴 => "문자열 리터럴"
+  - 템플릿 리터럴 => \`${변수} aa\`
+  - 객체 리터럴 => { propertyName : 1 }
+  - 함수 리터럴 => var a = function(x) { return x };
+
+## 3. Data type
+
+- 원시타입 **(Primitive Type)**: 자바스크립트에서 객체가 **(Reference Type)** 아닌 것들이며 값 그 자체로 저장된다.
+  - `Primitive types are immutable`
+  - String, Number, Boolean 같은 경우 객체가 존재 하지만, 원시타입의 리터럴로 정의하여 프로퍼티를 사용할경우 **Wrapper Object**로 자동 변환 되어 프로퍼티를 리턴한다. **(Auto Boxing)**
+    ```js
+      1.toString(); // "1"
+      new Number(1).toString(); // Wrapper Object 리턴후 property 값 리턴 내부에서 이루어진 평가이기 때문에 GC로 없어짐
+    ```
+    - 연산 이후, GC로 해당 Wrapper Object 삭제 (할당이 되어이 있지 않기 때문에)
+    ```js
+    "string".newProperty = 1; // no error
+    console.log("string".newProperty); // undefined
+    ```
+  - 하지만, `new 연산자로` 객체를 만들경우 Reference Type Objcet로 리턴되어 나와 **Primitive Type을 잃게 된다.**
+    - (원시 값을 갖고 싶으면, new String("값").valueOf() 사용 해야한다.)
+- Boolean
+- Null
+  - 산술 연산자에서는 '0'으로 평가
+- Undefined
+  - 산술 연산자에서는 'NaN'으로 평가
+- Number (IEEE754로 규정된 64-bit 부동소수점, 자바스크립트에는 정수 타입은 존재하지 않다.)
+  - 부호(1 bit), 지수(11 bit), 가수(52 bit)
+- String
+  - '+' 연산 외 '\*,/,%...' 연산자는 String 타입을 Number(String 타입)으로 연산을 하게된다.
+- Symbol (ECMAScript 6에 추가됨)
+
+### 3-1. typeof 연산자의 반환 값
+
+- | data             | ex                                        | return      |
+  | :--------------- | :---------------------------------------- | :---------- |
+  | 숫자, NaN        | 12,NaN, Number(12)                        | "number"    |
+  | 문자열           | "값", String("값")                        | "string"    |
+  | 논리값           | true, false                               | "boolean"   |
+  | 정의되지 않은 값 | undefined                                 | "undefined" |
+  | null 값          | null                                      | "object"    |
+  | 심벌             | Symbol("값")                              | "symbol"    |
+  | 함수 외의 객체   | [1,2,3], new String("값"), new Number(12) | "object"    |
+  | 함수             | function(){}                              | "function"  |
+
+- **객체의 이름까지 알고 싶을 때** `toString() 함수를` 이용하여 해당 타입을 확인할 수 있다.
+  ```js
+  function getType(target) {
+    return Object.prototype.toString.call(target).slice(8, -1);
+  }
+  ```
+
+### 3-2. 산술 연산
+
+- String 타입의 '+' 연산 방식을 제외하고 `대부분의 Data Type의` **'valueOf()'(우선순위 높음) 혹은 toString()으로 리턴된 값으로 연산을 한다.**
+- null은 0, undefined는 NaN으로 강제 형변환되어 연산한다.
+- `{} (block statements)` 에서 무엇이 반환되던지 **그것은 암묵적으로 0로 강제 형변환되어** `피연산자로` 사용된다.
+
+  ```js
+  null.valueOf(); // Error
+  null + 1; // 1
+  undefined + 1; // NaN
+  NaN + "stirng"; // "NaNstring"
+  {
+    3;
+  }
+  +1; // 1
+  {} + 1 // 1
+  1 + 1{} // 1[object Object]
+  ```
+
+### 3-3. {} block statements VS object literal
+
+- 블록 문장을 값이나 표현식으로 사용할 수는 없다.
+- console.log는 문장(statement)을 인자로 받아들일 수 없다.
+- 하지만, 오브젝트 리터럴은 인자로 받아들일 수 있다.
+- 문장(statements)은 어느것도 반환하도록 되어있지 않다.(값으로 리턴될 수 없기 때문)
+- 그래서 자바스크립트는 error을 내보내지 않는 대신에 `+ 연산자의 피연산자를` **숫자나 문자열로 바꾼다.**
+  - 만일 바꿀 수 없는 값이라면 에러를 리턴한다
+    > `블록 문장(block statements)`에서 무엇이 반환되던지 그것은 암묵적으로 **0로 강제 형변환되어 피연산자로 사용된다.**
+  - 여기서 생각은 문장이 끝났으므로 0이아닌 문장이 끝난걸로 인식하고 그다음 표현식을 실행했다고 생각이 든다.
+
+### 3-4. ==, === 비교
+
+- '==' 비교는 타입이 일치 하지 않을 때, 강제 타입으로 변환시켜 비교하게 된다.
+
+  ```js
+  77 == "77"; // => "77" => Number("77")로 변환 후 검사
+  false == 0; // => false => Number(false)로 변환 후 검사
+
+  null == null; // =>  서로 같으며 자기 자신과도 같습니다. => true
+  undefined == undefined; // =>  서로 같으며 자기 자신과도 같습니다. => true
+  null == undefined; // =>  서로 같으며 자기 자신과도 같습니다. => true
+  null == 0; // => false
+  undefined == 0; // => false
+
+  NaN == null; // 어떠한 값과도 동일하지 않다 false (Warning)
+  NaN == undefined; // 어떠한 값과도 동일하지 않다 false (Warning)
+  NaN == NaN; // 어떠한 값과도 동일하지 않다 false (Warning)
+  ```
+
+- '===' 비교는 `타입이일치 하진 않으면` **return false**, 타입이 `일치할 때` **값을 비교를 한다.** (Best Code)
+
+## 4. function
+
+```js
+function name(parameter(인자)) {}
+name(arguments(인수));
+```
+
+- parameter(인자)
+
+  - 유효범위는 지역함수 이며, 프로그램 실행하면서 필요한 변수 값
+
+- argument(인수)
+
+  - 함수에 인자값이 있지만, 인수를 안 보내도 함수는 실행이 된다.
+  - 해당하는 인자값을 모두 `undefined`로 정의 됨(lexcal Scope)
+
+- 지역 변수
+
+  - 함수내의 변수를 선언 할 수 있으며 안에서 식별자(var, const, let)로 선언한 변수들은 모두 지역 변수로 들어간다.
+  - 함수 안에 함수를 실행할 수 있다.(Nested Function)
+
+- return
+
+  - return이 없을 경우 undefined를 리턴 한다.
+
+- **JS에서는 함수가 객체이다.**
+
+  - 함수 선언문으로 함수를 선언하면 내부적으로는 그 함수 이름을 변수 이름으로 한 변수와 **함수 객체가 만들어지고,** 함수 객체의 참조가 저장 된다.
+
+## 5. object(instance)
+
+- **연관배열(associative array)** 또는 **맵(map),** **딕셔너리(Dictionary)** 라는 데이터 타입이 객체에 해당한다.
+- key, value 쌍으로 구성되어 있으며, key를 `해당하는(this)` 객체의 프로퍼티로 명한다.
+- 생성된 객체는 메모리(RAM-Heap)에 정의되며 해당하는 **주소값(Reference Type)을 저장하는 구조이다.**
+
+```javascript
+const 객체 리터럴 = {'propertyName': 10, 'propertyName(Method)': function(){ console.log(this.propertyName)}};
+
+var 객체 리터럴 = {};
+객체 리터럴['propertyName'] = 10;
+객체 리터럴['propertyName(Method)'] = function(){ console.log(this.propertyName) };
+delete 객체 리터럴['propertyName']; // property delete -> confiualable일 때만!!
+
+var 객체 생성자 = new 객체를 만들려는 함수명();
+객체 생성자['propertyName'] = 10;
+객체 생성자['propertyName(Method)'] = function(){ console.log(this.propertyName) };
+```
+
+### 5-1. 생성자
+
+- 앞에 예제 처럼 `new 연산자로` 객체를 생성시킨 함수를 생성자라고 한다.
+- 인스턴스는 **실체라는** 뜻이 있다.
+- 객체 지향 언어에서(ex. JAVA, C++) 인스턴스는 `클래스(설계도)로` 생성한 실체를 뜻한다.
+  - 하지만, JS에서는 **클래스가 없다.**
+  - 또한, 함수 자체도 **함수객체로** 만든 해당 **함수 인스턴스 이다.**
+  - 그래서, 생성자로 생성한 객체는 엄밀히 말해 인스턴스가 아니다.
+    - 하지만, 생성자가 클래스처럼 객체를 생성하는 역할을 담당하고 있어 **생성자로 생성한 객체도 인스턴스라고 부르는것이 관례이다.**
+
+### 5-2. this
+
+- 함수가 속해있는 객체를 가리키는 변수이다.
+- 함수를 어떻게 생성하냐에 따라서 달라질 수 있지만, 맥락에서는 function을 가지고있는 **객체 생성자(value Name), 객체 리터럴(value Name)** 를 말한다.
+
+## 6. array
+
+- 앞서 말한(Data type)에서도 원시 타입 이외는 모두 객체 참조이므로 array도 Array객체로 만들어진 **객체** 이다.
+- 즉, 배열 넘버링(index)이 key값으로 저장된것이다.
+  - 이 말은 즉, 여러 프로그래밍 언어에서 배열 요소는 **메모리에 연속된 공간에 저장 되지만, JS는 객체 그렇지 않다.**
+  - ES6에서 `TypedArray에서는` 연속된 공간에 저장된다.
+- 객체이기 때문에 delete가 가능한 프로퍼티가 있으면 **희소 배열로** 0 부터 시작되지 않은 배열이 만들어 질 수 있다.
+
+```js
+var a = [];
+a[1] = 2;
+a; // [empty, 2]
+a.length; // 2
+
+a.forEach((data, idx) => console.log(data, idx));
+// 2 1 => 0이 넘겨짐
+
+var s = a[Symbol.iterator]();
+for (a of s) console.log(a);
+// undefined
+// 2
+```
