## What it is
A React component wrapper around CodeMirror 6, providing a declarative, hook-friendly way to embed a code editor in React applications. It includes TypeScript support, theming, and extensions for building IDE-like editing experiences.

## Use cases
- embed a code editor in a React app
- build an in-browser IDE or playground
- add syntax-highlighted code input to forms
- create a markdown or JSON editor with live highlighting
- customize editor themes in React
- build a live coding demo component

## When to choose
- you use React and want CodeMirror 6 with a component/hook API
- you need TypeScript typings and easy theme integration
- you want a maintained wrapper instead of wiring CodeMirror manually

## When to avoid
- your app is not React-based
- you need CodeMirror 5 compatibility
- you need a full standalone editor application rather than an embeddable component
