Node.js is a JavaScript runtime built on Chrome's V8 engine. It was introduced by Ryan Dahl in 2009 and is widely used for backend services where event-driven I/O and a large JavaScript ecosystem matter. Common use: APIs, web servers, real-time apps, workers, CLIs, serverless functions. Interview angle: Expect questions about the event loop, async code, streams, package management, security, and production reliability.
