JavaScript Method within Method

Question

I would need to declare Methods within Methods and call them outside as a Object, Method connotation... To make it more clear:

I need to call:

Object.Method().nestedMethod();

how can I do it so? This failed so far:

function Object(){ 
     this.Method = function(){

          this.Method.nestedMethod = function(){

          };

     };

}

As I work on a DSL it is necessary to call a Method within a Method. In this case the last Method is some kind of recursion Method of the previous one, like this:

Object.execute(param).recursion();

How would I have to declare the nested Method to access this so?

Why exactly ? What's the real purpose ? Do you want, in fact, chaining ? — Denys Séguret

Yes, I writing some kind of DSL, and need to chain the Methods... And, I'm also giving parameters, so when calling Object.Method(param).nestedMethod(); - nestedMethod needs to know "param"... — user3865402

You can return an object that contains nestedMethod:

Object.Method = function () {
    return {
        nestedMethod: function () {}
    };
}

A new Object would be needed to call that (with a different name than "Object", hopefully)

Don't works really for me... Can you go more in detail?

@DamianT.Dziwis What does it return for you when you call Object.Method().nestedMethod();?

It returns nothing, I need to write a recursion function... Maybe this makes it more clear: Procedure.execute(param).loop(cycles); - so loop will call execute(param) in cycle times... Its necessary to do it nested...
