Node.js

Node.js is a powerful JavaScript runtime built on Chrome’s V8 JavaScript engine that allows you to run JavaScript on the server side. Unlike traditional server-side environments, Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, ideal for building scalable and high-performance applications.

Whether you're new to Node.js or looking to refine your skills, this page will provide all the resources you need to get started, explore advanced techniques, and optimize your Node.js applications for real-world use.
