Node.js is an open-source JavaScript runtime built on Chrome’s V8 engine that enables developers to create scalable and high-performance network applications. It uses an event-driven, non-blocking I/O model that makes it efficient for handling concurrent connections and real-time data processing. Node.js is widely adopted for server-side development, particularly for building web servers, APIs, and real-time applications. Its extensive ecosystem of modules and libraries, available through the npm (Node Package Manager) repository, supports a broad range of development needs and use cases.
