A debounce implementation in JS, with a default wait time. Useful when listening to window resize event for instance.

debounce.js

/* debounce(func,context,ms) returns a function that will be called only ms millisecond after it's latest call.
context and ms are optionnal.
*/
var debounce = (function(window){
  var defaultMs=300;
  return function (func,context,ms){
    var to;
    return function(){
      var args = Array.prototype.slice.call(arguments);
      if(!!to) clearTimeout(to);
      to = setTimeout(function(){
        func.apply(context || window,args);
      },ms || defaultMs);
    };
  };
})(window);
/*
Usage :
function myResizeHandler() {
  // magic here
}
var debouncedHandler = debounce(myResizeHandler);
window.addEventListener('resize',debouncedHandler);
*/
