Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code server-side. It uses the V8 JavaScript engine from Chrome and an event-driven, non-blocking I/O model, making it efficient for building scalable network applications like web servers and APIs.

Also known as: Node, NodeJS, Node JS, Nodejs, Node.js runtime

Why learn Node.js?

Developers should learn Node.js for building fast, scalable backend services, real-time applications (e.g., chat apps, gaming servers), and microservices architectures. It's particularly useful when using JavaScript across the full stack (e.g., with React or Angular on the frontend), as it enables code reuse and simplifies development workflows.
