What is Node.js?
Node.js is an open-source, cross-platform JavaScript runtime environment.
It allows you to run JavaScript outside of the browser, on the server side.

Traditionally: Frontend (JavaScript) + Backend (Java, Python, PHP).
With Node.js: Use JavaScript for both frontend and backend → faster development.
