## What it is
jsdom is a pure-JavaScript implementation of web standards like the WHATWG DOM and HTML Standards for Node.js. It emulates enough of a web browser environment to be useful for testing and scraping real-world web applications.

## Use cases
- parse and manipulate HTML in Node.js
- run DOM-based unit tests without a browser
- scrape web pages and query them with DOM APIs
- simulate a browser window for frontend code
- test JavaScript that relies on document and window

## When to choose
- you need a browser-like DOM environment in Node.js for testing
- you want to parse or scrape HTML using standard DOM APIs
- you're testing frontend libraries like React or jQuery without a real browser

## When to avoid
- you need full browser rendering, layout, or CSS visual behavior
- you need real network requests with full browser fidelity
- you're working outside Node.js or a JavaScript runtime

## Facets
- artifact type: library
- maturity: active
- function: parser, testing, web-scraping, http-client
- domain: web-development, frontend, testing, developer-tools, parsers
