How do I use IIFE in JavaScript?

IIFE stands for Immediately Invoked Function Expression. It's a function that runs as soon as it's defined. Would you like an example?

Yes, please provide an example of an IIFE.

Sure! Here's a simple example:

(function() {
    console.log('This is an IIFE!');
})();

This code will log 'This is an IIFE!' immediately.

What are the benefits of using IIFE?

IIFEs help in creating a private scope, avoiding global variable pollution, and can also be used for module patterns.

Can I pass parameters to an IIFE?

Yes, you can pass parameters to an IIFE just like a regular function. For example:

(function(name) {
    console.log('Hello, ' + name);
})('Alice');
