Trey Hendrickson Contract: Bengals’ Pass Rusher Seeks Long-Term Extension

Syntax: define() to define modules and ​ require() to import.
Use Cases: Widely used in browser-based JavaScript projects,‍ especially before ES ​modules became prevalent.
Example:

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

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

3. Worldwide 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.

4.ecmascript Modules (ESM)

The official standard module system for JavaScript, introduced with ES6 (ES2015). ESM uses ‌static analysis to ‌determine module dependencies,enabling optimizations and better tooling.

Syntax: import to import‍ modules ⁢and export to export.
Use Cases: Increasingly⁤ becoming the preferred module format ​for modern JavaScript development.
* Example:

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

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