scope - What way (if any) can I get the reference to anonymous function's closure in javascript?

Question

Let us consider the workable code:

var storage = {};

(function() {
    function internalMethod1() { ...; return; }
    function internalMethod2() { ...; return; }
    storage.storedMethod = internalMethod1;
})();

storage.storedMethod();

Is there any way to call internalMethod2, if it is not called in internalMethod1? In other words, can I access an anonymous closure from outside, if I have access only to one of its functions?

Answer 1

can I access an anonymous closure from outside?

No. Scopes are private in JS, and there's absolutely no way to access them from the outside (unless you use the engine's implementation-specific debugging API…).

Variables (including functions) are only available in the same scope and its children. If you want to access their values outside of the scope, you're at the mercy of the function to expose them in some way (return, assign to global storage variable etc).
