2. Create a function that takes 3 arguments and returns the sum of the three arguments.

3. Create a function named `colorCar` that receives a color, and prints out, "a red car" for example. (Hint: put it in your file and run it like before.)

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

3. 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)`

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

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

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

7. Change the function `vehicle` to use the list of question 5. So that `vehicle("green", 3, 1)` prints "a green new caravan".

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

9. What if you add one more vehicle to the list, can you have that added to the advertisement without changing the code for question 8?

10. Write a program to answer the following questions:

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

1. 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]

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!

function foo(func) {

// What to do here?

}

function bar() {

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

}

foo(bar);

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

var x = [1,2,3];

var y = [1,2,3];

var z = y;

What do you think will happen with x == y, x === y and z == y and z == x? Prove it!

Don't cheat! Seriously - try it first.

4. https://www.freecodecamp.com/challenges/record-collection

5. https://www.freecodecamp.com/challenges/iterate-over-arrays-with-map

var o1 = { foo: 'bar' };

var o2 = { foo: 'bar' };

var o3 = o2;

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

Does the order that you assign (o3 = o2 or o2 = o3) matter?

Have a look at https://javascriptweblog.wordpress.com/2010/09/27/the-secret-life-of-javascript-primitives/

'Coerce' means to try to change - so coercing `var x = '6'` to number means means trying to change the type to number temporarily.
