## What it is
Monaco Editor is the browser-based code editor that powers VS Code, distributed as an npm package with ESM and TypeScript API definitions. It provides models, views, and language services for rich in-browser code editing.

## Use cases
- embed a code editor in a web app
- build an online IDE or playground
- add syntax highlighting and IntelliSense to a browser text area
- create a JSON/YAML editor with validation in the browser
- build a custom VS Code-like editing experience on the web
- show editable code snippets with language support in documentation sites

## When to choose
- you need a full-featured code editor in the browser
- you want VS Code-grade editing features (multi-cursor, IntelliSense, diff view)
- you are building a web-based IDE or configuration editor

## When to avoid
- you need a lightweight plain textarea or simple markdown input
- you are building a native desktop or mobile editor rather than web
- you need a full IDE with terminal, debugger, and extensions rather than an editor component
