## What it is
CodeJar is a lightweight (~2.5 kB), dependency-free embeddable code editor for the browser built on contenteditable. It handles indentation, auto-closing brackets and quotes, Tab key handling, and undo/redo, while letting you plug in any highlighting library like Prism.js or highlight.js.

## Use cases
- embed a code editor in a web page
- add a lightweight code input box to a web app
- build an online code playground
- let users edit code snippets in the browser
- create a custom code editor with my own syntax highlighter
- replace CodeMirror with a tiny editor

## When to choose
- you need a tiny, dependency-free code editor in the browser
- you want full control over syntax highlighting via your own highlight function
- you need basic editing features like auto-indent, bracket closing, and undo/redo without a heavyweight editor

## When to avoid
- you need advanced IDE features like code folding, linting, or multi-cursor editing
- you need a full-featured editor with built-in language grammars and autocomplete
- you are building a non-browser (desktop or mobile-native) editor
