## What it is
Node.js is an open-source, cross-platform JavaScript runtime built on Chrome's V8 engine, enabling JavaScript to run outside the browser for servers, tools, and scripts. It is governed by the OpenJS Foundation with regular Current and LTS releases following semantic versioning.

## Use cases
- run javascript on the server
- build a backend api in javascript
- write command-line tools with node
- host a realtime websocket server
- script build tooling in javascript
- run a local development web server

## When to choose
- you want a mature, widely supported JavaScript runtime with LTS guarantees
- you need an event-driven, non-blocking server for I/O-heavy workloads
- your team already knows JavaScript and wants one language across stack
- you rely on the npm ecosystem of packages

## When to avoid
- you need heavy CPU-bound computation without worker threads
- you require strict per-request memory isolation or multithreading by default
- your team standardizes on another runtime like Deno or Bun for its features

## Facets
- artifact type: application
- maturity: stable
- function: http-server, developer-tools, cli, concurrency, interpreter
- domain: developer-tools, backend, web-development, cross-platform
- platform: windows, cross-platform, cli
- tags: javascript-runtime, v8, event-loop, lts, openjs-foundation, npm-ecosystem, command-line, linux, macos
