Can someone please explain in simple terms what this does? I looked up but didnt really understand.

First thing is the console.log. I often see this. What does it mean? Then the id.split part is confusing too. 

console.log(id);
 id = id.split(" ");

  • You print the id to the console, and then convert the string to an array by splitting it whereever there's a space. – arao6 Nov 09 '14 at 15:32

    2 seconds on Google: [`console.log()`](https://developer.mozilla.org/en-US/docs/Web/API/Console.log) and [`String.prototype.split()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split) – h2ooooooo Nov 09 '14 at 15:33

console.log writes the value to the JavaScript Console.

id.split(" ") splits the string id at the space into an array.

var id = "This is a string";
var idParts = id.split(" ");

for(var i = 0; i < idParts.length; i++) {
  console.log(idParts[i]);
}

The above will output "This", "is", "a", and "string" to the javascript console.

Console.log will print the id to the console. And split function will split the string into multiple arrays.

For example if id = "I love stackoverflow"; If you use

id.split(" ")

will result in an array with 3 components: "I", "love" and "stackoverflow".
