Javascript review for jQuery
Fundamental Functions

Functions are the fundamental unit of action in jQuery. The main entry point of most jQuery applications is a block of code that looks like

$('document').ready(function() {
    //do something;

An understanding of JavaScript functions will help you to get the most out of jQuery.

There are two ways to define a function but we've been mainly showing you this approach:

var myFunction = function() {
    //do something;

We use this method because it is slightly more flexible than the other approach but the differences are not that important.


Write two functions:

  1. sayHello() that returns just "hello"
  2. multiplyThree(x,y,z) which takes three numbers and returns the product of all three of them multiplied together. So multiplyThree(3,5,7) should return 105.
