Javascript vendor prefixer

prefix.js

// Source: Another gist, will update if I can get the link

// Replace # with the first letter of the function
["#","webkit#","moz#","ms#","o#"].reduce(function(p, v) { return window[v + p] || p; }, "#FUNCTION_NAME");

// E.g. requestAnimationFrame (vendor prefix not needed anymore)
["r","webkitR","mozR","msR","oR"].reduce(function(p, v) { return window[v + p] || p; }, "equestAnimationFrame");
