Node.js

nodejs.org

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. Built on Chrome's V8 JavaScript engine, Node.js enables developers to use JavaScript for server-side scripting, allowing for the development of scalable network applications. Its event-driven, non-blocking I/O model makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js has a vast ecosystem of open-source libraries available through npm (Node Package Manager), one of the largest software registries in the world. It's widely used for building web servers, command-line tools, and various types of applications, especially those requiring real-time features like chat applications, streaming services, and APIs.
