Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser, primarily on the server-side. It uses the V8 JavaScript engine from Chrome and provides an event-driven, non-blocking I/O model, making it efficient for building scalable network applications. It includes a built-in package manager (npm) and a rich ecosystem of libraries and frameworks.

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

Why learn Node.js?

Developers should learn Node.js for building fast, scalable server-side applications, such as web servers, APIs, real-time applications (e.g., chat apps), and microservices, due to its non-blocking architecture and JavaScript unification across front-end and back-end. It is particularly useful in scenarios requiring high concurrency, like streaming services or IoT applications, and benefits from a vast npm ecosystem for rapid development.
