Nodejs

Node.js is a framework for building scalable server-side applications and network programs using asynchronous JavaScript. It has a non-blocking I/O model that uses a single-threaded event loop which improves speed and reduces memory usage. Key benefits include its fast performance, non-blocking I/O, small memory footprint, use of the V8 JavaScript engine, and ability to be used for both frontend and backend development through its reactive programming approach.
