JavaScript modules are fundamental to modern web development, enabling organized code structure and reusability. Here's a breakdown of key concepts:

📚 What Are JavaScript Modules?

Modules allow you to encapsulate code into reusable components. Think of them as building blocks for your application!

  • Encapsulation: Hide implementation details
  • Reusability: Share code across projects
  • Maintainability: Simplify code management

🔧 Module Systems in JavaScript

JavaScript has evolved several module systems:

  1. CommonJS (Node.js)
  2. ES Modules (ES6+) ⚡
  3. AMD (Asynchronous Module Definition)
  4. UMD (Universal Module Definition)

Each system has its use cases. For example, ES Modules are now the standard in modern browsers!

🧠 Module Types & Patterns

Common module patterns include:

  • IIFE (Immediately Invoked Function Expression)
  • AMD for asynchronous loading
  • ESM for tree-shaking and bundling

🛠 Best Practices

  • Use export and import for clarity
  • Avoid global variables
  • Optimize for tree-shaking with ESM
