IIFEs help in creating a private scope, avoiding global variable pollution, and can also help in module pattern implementation.

Absolutely! Here's a simple example: (function() { console.log('Hello, IIFE!'); })(); This will log 'Hello, IIFE!' immediately.
Are IIFEs still relevant in modern JavaScript?
