What are some real-world uses of module patterns in programming?

Module patterns are used to encapsulate code, manage dependencies, and create reusable components. For example, in JavaScript, they help in organizing code into self-contained modules.

Can you give me an example of a module pattern in JavaScript?

Sure! A common example is the Revealing Module Pattern, where you define a module and expose only certain methods. Here's a simple example:

const Counter = (function() {
    let count = 0;
    return {
        increment: function() { count++; },
        getCount: function() { return count; }
    };
})();

What are the benefits of using module patterns?

The benefits include better code organization, reduced global namespace pollution, improved maintainability, and easier testing.

Are there any downsides to using module patterns?

Yes, potential downsides include increased complexity and the need for a deeper understanding of closures and scope.
