So If I have a self-executing function and I want to access a variable in another self executing function is there anyway to do this?

If their is a way, Is their a way without it being a reference to the original?

Code:
(function () {
    
    var accessMe = "Hello World"; // What I want to grab

})();


(function () {

    accessMe = "Goodbye World"; // What I want to change to

})();
