JS Time Events

setTimeout(function, milliseconds) Executes a function, after waiting a specified number of milliseconds.

setInterval(function, milliseconds) Same as setTimeout(), but repeats the execution of the function continuously.
window.clearInterval(timerVariable) stops the executions of the function specified in the setInterval() method.

JS cookie

(JavaScript can create, read, and delete cookies with the document.cookie property.)
document.cookie = "username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 UTC"; to create
var x = document.cookie; to read
>>> document.cookie will return all cookies in one string much like: cookie1=value; cookie2=value; cookie3=value;
