This is a programming article, so if you don't understand JavaScript, don't care about JavaScript, or don't care about Immediately-Invoked Function Expressions (IIFE's), this article will probably mean nothing to you.

Now that that's out of the way, let's make sure we're all on the same page here. An Immediately-Invoked Function Expressions (IIFE) is the following:

(function () {

It's a private scope that's created within the code that will run immediately upon its code being read. This has applications, yes, and from personal experience, there are times where its useful, too.

However, there's been a trend in the RPG Maker community, especially amongst plugin developers, that argue that entire plugins need to be wrapped around in an IIFE. I personally don't believe that. In fact, doing such a thing will often lead to problems later down the road especially if a plugin library gets bigger and bigger.
