map() Array Method in JavaScript

Way cooler than using for loops on arrays, map() iterates over an array and creates a new array that has had each item passed through a function:

var drinks = [“coffee soda”, “tea”, “whiskey”];

var coldDrinks = {
	return ‘iced ’ + drink;

// [‘iced coffee soda’, ‘iced coffee’, ‘iced whiskey’]

The syntax is very simple:

var newArray =;
