Introduction to Modules in JavaScript

Modules in JavaScript allow you to split code into smaller, reusable files.
This makes it easier to organize large projects.

Exporting a Module

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

// file main.js
import { add } from './operations.js';

console.log(add(5, 7)); // 12

// file greeting.js
export default function greet(name) {
  return `Hello, ${name}`;
}

// file app.js
import greet from './greeting.js';
console.log(greet("Carlos"));

With modules, you can keep your code clean and easy to maintain.
