## What it is
A React component that renders text and code diffs in split or inline views, built on top of jsdiff. It supports word-level diffing, line highlighting, and customization of styles and themes.

## Use cases
- show code changes in a react app
- display side-by-side text diff component
- compare two versions of a file in the browser
- render github-style diff viewer in react
- highlight word-level changes between strings
- code review diff ui component

## When to choose
- you need a drop-in React component for displaying text or code diffs
- you want split or inline diff views with word-level highlighting
- you need a customizable, lightweight diff viewer inspired by GitHub's UI

## When to avoid
- you need to compute or parse diffs outside a React UI
- your project is not React-based
- you need full file-system or git repository diffing rather than string comparison

- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: frontend, web-development, developer-tools, version-control
