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

For performance purposes you can invoke it this way:

var a = (function(){
   function _a(){}
   _a.prototype = (function(){
     var _test = function(){ console.log("test"); };
     return {
       test: _test
     }
   }());

  return new _a();
}());

// usage
var x = a;
x.test(); // "test"
