I read somewhere that it is absolutely impossible to attain a reference to a scope. Are there any hacks to get a reference to a scope and 'trap' it inside a variable?

EDIT:

I know I can acquire the global scope through the window object. I am referring to dynamically creates scopes of functions and so fourth.

    far too vague a question without examples. scope/closure is not a trivial concept – charlietfl Dec 21 '14 at 17:50

    Other than a native extension of the JavaScript engines, no. None of the major engines current offer direct exposure of [lexical environments](http://www.ecma-international.org/ecma-262/5.1/#sec-10.2) or [environment records](http://www.ecma-international.org/ecma-262/5.1/#sec-10.2.1) to JavaScript code. – Jonathan Lonowski Dec 21 '14 at 17:52

Refrence to windows object/global scope inside variable can be like this. Here i assume you are in global scope 

 var reftowindows = this;

I am referring to dynamically creates scopes of functions and so fourth.

Function defined at global scope

function returnRefrence(){
var refvar = this;
return this;

}

Calling function return variable holding refrence to window as scope

console.log(returnRefrence()); // console logs "window" object

Calling function with call() and binding it to object changes the scope and returns variable holding refrence to obj as scope

 obj = {};
 console.log(returnRefrence.call(obj)); // console logs "obj" object
