What is the module pattern in JavaScript?

The module pattern is a design pattern that helps in organizing code by encapsulating it within a function scope, creating private and public members.

Can you give me an example of how to implement the module pattern?

Sure! Here's a simple example:

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

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

What are the benefits of using the module pattern?

The module pattern helps in avoiding global scope pollution, provides better organization of code, and allows for encapsulation of private data.

Are there any drawbacks to using the module pattern?

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