# Node.js

> Run JavaScript on servers and build command line tools

Node.js is an open-source runtime that lets developers run JavaScript outside the browser. It uses the V8 engine and an event loop with asynchronous input and output, allowing a server to handle multiple connections while waiting for network or file operations. Developers use it for web servers, APIs, command line utilities, and automation scripts, with the option to use JavaScript across both browser and server code.

The standard library includes modules for HTTP, files, streams, cryptography, and worker threads, along with a built-in test runner. A project can start with a JavaScript file run from the terminal, then add reusable packages through npm as needed. Node.js is available across major operating systems and can support anything from a small local script to the backend of a web application.
