Describe the module patterns in JavaScript and discuss their advantages and use cases.

JavaScript module patterns provide a way to encapsulate and organize code. Common patterns include the Revealing Module Pattern, CommonJS, and ES6 Modules.

The Revealing Module Pattern is advantageous for maintaining a clean API while keeping implementation details private. CommonJS is useful for server-side development, allowing modular code with 'require' and 'module.exports'. ES6 Modules are the modern standard, offering a clean syntax and support for asynchronous loading, making them suitable for both client and server-side applications.

Choosing a module pattern depends on the project's needs and the environment in which the code will run.
