Syntax: define() to define⁤ modules and require() to import. Use Cases: Historically popular in browser-based JavaScript growth, especially with libraries like RequireJS.
Example:

javascript
    // moduleA.js
    define(function() {
      return function() {
        console.log("Hello from Module A!");
      };
    });

    // moduleB.js
    define(['./moduleA'], function(moduleA) {
      moduleA();
    });
    

3. Global Module Definition (UMD)

UMD aims to be compatible with both CommonJS and AMD, providing a single module format that works in various environments.⁣ It attempts to detect the‍ module ​system and adapt accordingly.

Syntax: A wrapper function that checks⁢ for‍ different module environments.
Use Cases: Useful ⁤for creating libraries that need to work⁣ in both Node.js and the⁤ browser.
Complexity: Can be more complex to write than CJS or AMD⁢ directly.

Syntax: import ⁣ and ​ export keywords.
Use cases: The modern standard for JavaScript modules, widely supported in browsers and Node.js.
Example:
​ ```javascript
// moduleA.js
export function sayHello() {
⁤ console.log("Hello from Module A!");
}

// moduleB.js
import { sayHello } from './moduleA.js';
