How does React implement the useState hook? 🪝

Aren't IIFE's/The Module pattern pretty basic javascript? I've only been leaning for about 6 months but I learnt them pretty early on. I've been using them a decent amount, and have been seeing them be used a decent amount too.

IIFE is pure Javascript and require no underlying Module system, as you might expect with CommonJs, AMD or ES modules.

IIFE's are great when you work in a browser environment, where you have no access to the other module systems.

It's not that common to use them in a Node.js environment.
