Node.js

intermediate

JavaScript, but on the server.

Node.js is a runtime that runs JavaScript outside the browser, powered by Chrome's V8 engine. It's event-driven, non-blocking, and perfect for I/O-heavy workloads. It's also the reason you can write your frontend and backend in the same language.
