Accessing variables trapped by closure

Question

I was wondering if there is any way to access variables trapped by closure in a function from outside the function; e.g. if I have:

A = function(b) {
    va         


        

Answer 1

If you only need access to certain variables and you can change the core code there's one easy answer that won't slowdown your code or reasons you made it a closure in any significant way. You just make a reference in the global scope to it basically.

(function($){
    let myClosedOffObj = {
        "you can't get me":"haha getting me would be useful but you can't cuz someone designed this wrong"
    };
    window.myClosedOffObj = myClosedOffObj;
})(jQuery);
myClosedOffObj["you can't get me"] = "Got you now sucker";

This will work with functions or "methods" too.
