Node.js
Node.js is a runtime that lets JavaScript run on servers, not just in browsers. It powers APIs, build tools, and frameworks like Next.js.
Example
A website's contact form sends data to a small Node.js API, which saves it to a database and notifies the team.
Why it matters
With Node.js, one language covers the front end and back end, so teams move faster with fewer specialists.
