Node.js Tutorial

Welcome to the Node.js tutorial! This guide will help you get started with Node.js, a powerful JavaScript runtime built on Chrome's V8 JavaScript engine.

What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that enables developers to run JavaScript code outside a browser. It's built on Chrome's V8 JavaScript engine and uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.

Features of Node.js

Non-blocking I/O: Node.js uses non-blocking I/O calls, which makes it highly scalable and efficient.
Asynchronous programming: Node.js is designed with an event-driven architecture, which makes it easy to write code that runs asynchronously.
Rich ecosystem: Node.js has a vast ecosystem of packages and modules, making it easy to extend its functionality.
