What is Node.js?
Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to build server-side and networking applications. It uses an event-driven, non-blocking I/O model, making it efficient and lightweight, especially for real-time applications. Node.js is built on Chrome’s V8 JavaScript engine and is widely used for creating scalable and high-performance web applications.
