Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code server-side. It uses an event-driven, non-blocking I/O model, making it efficient for building scalable network applications, particularly web servers and APIs. It is built on Chrome's V8 JavaScript engine and includes a rich ecosystem of packages via npm (Node Package Manager).

Also known as: Node, NodeJS, Node Js, Node.js API, Node API

Why learn Node.js?

Developers should learn Node.js when building real-time applications, APIs, microservices, or server-side web applications due to its high performance and scalability. It is ideal for I/O-intensive tasks like handling multiple concurrent connections, such as in chat apps, streaming services, or RESTful APIs, and benefits from JavaScript's ubiquity for full-stack development. Use cases include creating backend services, command-line tools, and serverless functions.
