//OBJECTS METHODS

//1. Object.keys(abj) -Returns an array of objects keys(property names)

const user = {

id: 1,

name: "David",

age: 40

}

console.log(Object.keys(user))//[ 'id', 'name', 'age' ]

//2. Object.values(abj)-Returns an array of an object values

const user2 = {

id: 2,

name: "Robert",

age: 50

}

console.log(Object.values(user2))//[ 2, 'Robert', 50 ]

//3.Object.entries(obj)-Returns an array of key-value pairs

const user3 = {

id: 3,

name: "Kim",

age: 20

}

console.log(Object.entries(user3))//[ [ 'id', 3 ], [ 'name', 'Kim' ], [ 'age', 20 ] ]

//4. Object.freeze(obj) -Prevents modification of an object

const user4 = {

id: 1,

name: "Ann",

age: 25

}

Object.freeze(user4)

user4.name = "Sarah"//wont change the object value

user4.age = 35//won't change object value

console.log(user4)//{ id: 1, name: 'Ann', age: 25 }

//5.Object.seal()-Prevents adding/removing properties, but you can still update existing values.

const user5 = {

name: "Alice",

age: 25

};

Object.seal(user);

user.age = 30; // works

user.city = "Nairobi"; // wont add

console.log(user); // { name: "Alice", age: 30 }

//6.Object.assign()-Copies values from one object to another.

const user6 = {

name: "Alice"

};

const details = {

age: 25,

city: "Nairobi"

};

const merged = Object.assign({}, user, details);

console.log(merged);// { name: "Alice", age: 25, city: "Nairobi" }

//7. Object.hasOwn() (or hasOwnProperty) -Checks if an object has a specific property.

const user7 = { name: "Alice", age: 25 };

console.log(Object.hasOwn(user7, "name")); // true

console.log(Object.hasOwn(user7, "city")); // false
