Question

If you have something like that :

var ASK = (function (){
   var i = 0, _this = this;
   function private(){
      console.log(i++)
   }
   return {
      call : function (methodName, args){
         eval(methodName + '(' + args + ')' );
      }
   }
})();

ASK.call('private');

It’s possible to call a function inside ASK scope without using eval ? And why when i try use _this[method]() I get that it’s not a function ? Does _this shouldn’t refer to scope inside ASK = (function(){})?

Answer 1

Use object:

var ASK = (function (){
   var i = 0, _this = this;
   var myFuncs = {
       private: function(){
          console.log(i++)
       }
   }
   return {
      call : function (methodName, args){
         myFuncs[methodName](args);
      }
   }
})();

ASK.call('private');
