Node.js allows developers to run JavaScript directly on a computer or server instead of just inside a web browser. It is completely free, open-source, and runs on Windows, Mac, and Linux. This means you can build full websites using only JavaScript.
Key Points
- Node.js runs on the server, not the browser.
- It handles tasks asynchronously without waiting.
- It uses a fast, single-threaded architecture.
- Developers use it to build fast, scalable applications.
