Node.js
Environnement d'exécution JS.
Node.js is built on Chrome's V8 JavaScript engine. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

A tool that lets your computer run [JavaScript](/fr/terms/javascript) code by itself, not just inside a browser like Chrome or Safari. It's like giving JavaScript its own engine to drive a car.
🤓 Expert Deep Dive
Uses the Libuv library to handle asynchronous I/O. Operates on a single-threaded event [loop](/fr/terms/event-loop), but can handle thousands of concurrent connections. Key modules include 'fs', 'path', and 'http'.
