## What it is
Marked is a fast, low-level markdown parser and compiler written in JavaScript that converts markdown to HTML. It has zero dependencies, supports custom extensions, and works in the browser, on a server (Node.js), or as a CLI tool.

## Use cases
- convert markdown to html in node.js
- render markdown in the browser
- parse markdown files from the command line
- build a markdown editor with live preview
- render user-generated markdown content in a web app
- extend markdown with custom syntax

## When to choose
- you need a fast, lightweight markdown-to-HTML converter with zero dependencies
- you want to run the same parser in browser, server, and CLI environments
- you need to extend markdown with custom syntax via extensions

## When to avoid
- you need sanitized HTML output - marked does not sanitize and requires a library like DOMPurify
- you need strict CommonMark compliance above all else
- you need markdown parsing with built-in caching
