3. Create an object and a function that takes the object as a parameter and prints out all of its names and values.

4. Create a function named `vehicleType` that receives a color, and a code, 1 for car, 2 for motorbike. And prints "a blue motorbike" for example when called as `vehicleType("blue", 2)`

5. Can you write the following without the `if` statement, but with just as a single line with `console.log(...);`?

6. Create a function called `vehicle`, like before, but takes another parameter called age, so that `vehicle("blue", 1, 5)` prints "a blue used car"

7. Make a list of vehicles, you can add `"motorbike"`, `"caravan"`, `"bike"`, or more.

8. How do you get the third element from that list?

9. Change the function `vehicle` to use the list of question 4. So that `vehicle("green", 3, 1)` prints "a green new caravan".

10. Use the list of vehicles to write an advertisement. So that it prints something like: `"Amazing Joe's Garage, we service cars, motorbikes, caravans and bikes."`. (Hint: use a `for` loop.)

11. What if you add one more vehicle to the list, can you have that added to the advertisement without changing the code for question 7?

12. Create an empty object

13. Create a function that takes two objects as parameters and compares them. You will actually need to write two functions — one that compares with `==` and one that compares with `===`. Remember that objects can have objects inside of them so you'll need to find a way to compare every element of every object (types and values). For example:

var obj1 = {

a: 1,

b: 'this is the letter b',

c: { foo: 'what is a foo anyway',

bar: [1,2,3,4]

}

}

var obj2 = {

a: '1',

b: 'this is the letter b',

c: { foo: 'what is a foo anyway',

bar: [1,2,3,4]

}

}

In our example we'll say that `obj1 == obj2` is `true` and `obj1 === obj2` is `false`. Make sure you can see why before you write any code!

Note: give this exercise your best shot but don’t spend more than, say, one hour on it.

14. We saw that we can pass functions as arguments to other functions. Your task is to write a function that takes another function as an argument and runs it.

function foo(func) {

// What to do here?

}

function bar() {

console.log('Hello, I am bar!');

}

foo(bar);

15. Write some code to test two arrays for equality using `==` and `===`. Test the following:

16. Take a look at the following code:

var o1 = { foo: 'bar' };

var o2 = { foo: 'bar' };

var o3 = o2;

Show that changing `o2` changes `o3` (or not) and changing ~~`o2` changes `o3`~~ `o1` changes `o3`(or not).

Does the order that you assign (`o3 = o2` or `o2 = o3`) matter? {Jim Cramer: ???}

17. What does the following code return? (And why?)
