Honestly I have no clue what I did here.

It's not black magic, but let me explain:
we have a simple function were we pass 2 arguments (Joomla and window) both defined (the first on a line above the function declaration and the other one from the browser)

function( Joomla, window) { }

Now that function we want to be contained in an IIFE (Immediately-Invoked Function Expression) which has a very nice advantage as we don't end up with global variables. So a simple IIFE is like:

(function() {})();

But in our case we need to pass some arguments to the function so we do that like:

(function( Joomla, window) {})(Joomla, window);

I hope this is helpful
