Edit:
"real code for better context":
(function() {var requestAnimationFrame = window.requestAnimationFrame || window.mozRequestAnimationFrame || window.webkitRequestAnimationFrame || window.msRequestAnimationFrame;
window.requestAnimationFrame = requestAnimationFrame;
})();
Edit:
Didn't know it was called IIFE, thank you for the links.
