What are the best practices for using the module pattern in JavaScript?

The module pattern is great for encapsulating code. Best practices include using IIFE (Immediately Invoked Function Expressions) to create a private scope, exposing only the necessary methods and properties.

Can you give me an example of how to implement it?

Sure! Here's a simple example:

const MyModule = (function() {
    let privateVar = 'I am private';
    return {
        publicMethod: function() {
            console.log(privateVar);
        }
    };
})();

MyModule.publicMethod(); // Outputs: I am private

What are the advantages of using the module pattern?

The advantages include better organization of code, avoiding global namespace pollution, and improved maintainability.

Are there any downsides to using it?

Yes, one downside is that it can lead to larger file sizes if not managed properly, as each module may include its own scope.
