Node.js is a server-side JavaScript runtime built on Chrome’s V8 engine, used to build fast, scalable web applications and APIs.
Its non-blocking, event-driven architecture makes Node.js ideal for handling concurrent requests — such as in chat apps, real-time dashboards, and microservices. It’s commonly used with Express.js, MongoDB, and various cloud platforms for full-stack JavaScript development.
Thanks to npm (Node Package Manager), developers have access to a massive ecosystem of reusable modules, which accelerates development and simplifies complex functionality.
