Node.js is a powerful, open-source JavaScript runtime built on Chrome’s V8 engine, designed for building fast and scalable server-side applications. It uses an event-driven, non-blocking I/O model, making it ideal for real-time applications like chats and APIs. With npm (Node Package Manager), developers have access to a vast library of modules. Node.js supports full-stack development with JavaScript. We can also work on this technology to deliver high-performance and efficient web solutions.
