How do I use IIFE in JavaScript modules?

What is an IIFE and how can I use it in JavaScript modules?

An IIFE, or Immediately Invoked Function Expression, is a function that runs as soon as it is defined. In JavaScript modules, you can use IIFE to create a private scope for your variables and functions.

Can you show me an example of using IIFE in a module?

Sure! Here's a simple example:

const myModule = (function() {
    let privateVar = 'I am private';
    return {
        getPrivateVar: function() {
            return privateVar;
        }
    };
})();

console.log(myModule.getPrivateVar()); // Outputs: I am private

What are the benefits of using IIFE in modules?

Using IIFE in modules helps to avoid polluting the global scope, encapsulates variables, and maintains a clean code structure.

Are there any downsides to using IIFE?

One downside is that it can make debugging more challenging since variables are not accessible outside the IIFE. Additionally, it may add complexity to your code.
