adding callback to function - always

Question

I found myself using a weird way to add callback functions to my functions and I was wondering if there is a more generic way to add callbacks to functions, best case I would ha

Answer 1

You could, if you really want to, extend Function.prototype with a .cb prototype. Something like:

Function.prototype.cb = function(cb){
   var self = this;
   return function(){
      self.callback = cb || function(){};
      self.apply(self, arguments);
   }
}

then your code would compress to:

var myFunc = function(obj){
   // some code

   this.callback(); // callback will always be defined
}

and the call would slightly change:

myFunc.cb(function(){
   // callback code
})(myObj);

Just an idea. You can make the syntax pretty much whatever you want.
