Arrow Functions (Fat Arrows)

Arrow functions create a concise expression that encapsulates a small piece of functionality. Additionally, arrows retain the scope of the caller inside the function eliminating the need of self = this.

Example

// const multiply = function(x,y) {

	<!DOCTYPE html>
	<html lang="en">
	<head>
	<title></title>
	<meta http-equiv="Content-Security-Policy" content="default-src https://ajax.googleapis.com; child-src 'none'; object-src 'none';">

	</head>
	<body>
	<h1>test</h1>
	<script>
