JavaScript - Declaring Global Scope for Nested Function?

Question

My attempts at giving global scope to a nested JavaScript function are not working:

//DECLARE FUNCTION B IN GLOBAL SCOPE
function B;

function A() {

    //DEFIN

You're close, but not completely correct.

1. You have to define B as a variable and then assign a function to it.
2. Also run A() before executing B, otherwise B will be undefined. The easiest way of running it is the way that I show in my code example.

These are the smallest amount of changes to your code to make it work as you asked:

var B;

(function A() {
    // define function B
    B = function() {
        alert("function B is running");
    }
})();

// call function B globally
B();
