Welcome to the JavaScript Modules documentation! 🌟 Here you'll find essential guides on working with modules in JavaScript.

📚 What Are JavaScript Modules?

JavaScript modules are files that contain code which can be reused across different parts of an application. They help organize code and improve maintainability. ⚙️

  • Module Definition: Use export to share functions, classes, or variables.
  • Module Usage: Import components with import statements.
  • ES6 Modules: Modern standard for modular code (.mjs files).
  • CommonJS: Older standard used in Node.js (.js files).

🧩 Example: Creating a Module

// mathUtils.js
export function add(a, b) {
  return a + b;
}

export function multiply(a, b) {
  return a * b;
}

🛠️ Best Practices

  • Keep modules focused on a single responsibility. 📌
  • Use descriptive names for modules and exports. 📝
  • Avoid global variables by encapsulating code. ⚠️
