Node.js

The runtime that lets JavaScript run outside the browser, powering development tools and servers.

Detailed Explanation

Think of Node.js like shipping JavaScript beyond its original home in web browsers. Just as a browser is a container that runs JavaScript code, Node.js is a different runtime that lets you run JavaScript on servers and your computer.

Node.js powers the entire JavaScript development ecosystem: npm (package management), build tools, development servers, and backend applications. When you run npm install or start a dev server, Node.js is doing the work behind the scenes.

Node.js comes with its own CLI tools and a rich ecosystem of packages. Claude Code, Supabase Edge Functions (via Deno, a Node.js alternative), and most modern frameworks rely on Node.js for development tooling.
