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

Module patterns help in organizing code and avoiding global scope pollution. Key practices include using IIFE, keeping modules small, and exposing only necessary methods.

Can you explain what an IIFE is?

An IIFE, or Immediately Invoked Function Expression, is a function that runs as soon as it is defined. It's often used to create a private scope.

How do I expose methods from a module?

You can expose methods by returning an object from your module that contains references to the methods you want to make public.

What are some common mistakes to avoid with module patterns?

Common mistakes include exposing too many methods, not using closures effectively, and failing to maintain a clear structure.
