Node.js is a cross-platform, open-source server environment that can run on Windows, Linux, Unix, macOS, and more. Node.js is a back-end JavaScript runtime environment, that runs on the V8 JavaScript Engine, and executes JavaScript code outside a web browser.
Node.js is widely used for the back-end of applications, like using Express.js to build the back-end of classic web applications. Also, it is used for server-side programming and non-blocking, event-driven servers like typical websites and backend API services.
