Node.js is an open-source, server-side JavaScript runtime built on the V8 JavaScript Engine. It allows developers to execute JavaScript outside the browser, making it possible to build scalable backend services and APIs using JavaScript.

Node.js is known for its non-blocking, event-driven architecture, which makes it highly efficient for handling multiple requests simultaneously. It is widely used for building real-time applications such as chat apps, streaming services, and REST APIs.
