Node.js: A Beginner's Guide

Node.js is a powerful JavaScript runtime built on Chrome's V8 JavaScript engine. It allows developers to build scalable network applications using JavaScript on the server side.

What is Node.js?

Node.js is an open-source, cross-platform runtime environment that executes JavaScript code outside a web browser. It is designed to build scalable network applications and is particularly well-suited for I/O-heavy tasks.

"Node.js allows developers to use JavaScript for server-side programming, unifying the development process."

Getting Started with Node.js

To get started with Node.js, you need to install it from the official website. Once installed, you can create a simple server:

const http = require('http'); const server = http.createServer((req, res) => { res.statusCode = 200; res.setHeader('Content-Type', 'text/plain'); res.end('Hello World!'); }); server.listen(3000, () => { console.log('Server running at http://localhost:3000/'); });

Benefits of Using Node.js

• High performance: Built on the V8 engine, Node.js is fast and efficient.
• Scalability: Easily handle multiple connections simultaneously.
• JavaScript everywhere: Use the same language for both client-side and server-side development.

Node.js is a powerful tool for building modern web applications, and its popularity continues to grow.
