Introduction to the Node.js Module System

Modules are at the heart of every Node.js application. Here’s how they work:

1️⃣ Built-in Modules:
Node.js comes with modules like:

fs for file handling
http for creating servers
path for file paths

2️⃣ Custom Modules:
Create a module by exporting code:

// myModule.js

module.exports = function greet() {

console.log("Hello from my module!");

};

Use it in another file:

const greet = require('./myModule');

greet();

3️⃣ Third-Party Modules:

Install libraries via npm:

npm install express

Import it using require().

The module system ensures clean, maintainable, and scalable applications. What’s your go-to module in Node.js?
