// Use it like:

var myQueue = new TimedQueue(800);

// Call this 100 times in less than 500 ms:
myQueue.push(myCallback);

// myCallback function will be called only once, exactly 800 ms after the last call to 'push'

timed_queue.js

var TimedQueue = function(timeout) {
  var identifier = null;

  this.push = function(callback) {
    window.clearTimeout(identifier);
    identifier = setTimeout(callback, timeout);
  };
};
