Decorator to limit function calls to every `cd` ms

throttle.js

var throttle = function(f, cd) {
  var _cd = new Date;
  return function() {
    if (_cd - new Date < 0) {
      _cd = new Date(new Date().getTime() + cd);
      return f.apply(this, arguments);
    }
  };
};

/*

var shout = throttle(function() { console.log('SHOUT!'); }, 1000);
setInterval(shout, 100);

*/

try +new Date() instead of .getTime() :) or even cd + new Date()
