Exposing a method which is inside a closure

Question

When we are creating a method inside a closure it becomes private to that closure and can\'t be accessed until we expose it in some way.

How can it be exposed?

Answer 1

You can return a reference to it...

var a = function() {

   var b = function() {
      // I'm private!
      alert('go away!');
   };

   return {
      b: b // Not anymore!
   };

};

See it on jsFiddle.

You could also bind it to the window object. But I prefer the method above, otherwise you are exposing it via a global variable (being a property of the window object).
