## What it is
The official React comment box example code from the React tutorial, demonstrating basic React usage with a simple comments API. It includes server implementations in Node, Python, Ruby, PHP, Go, and Perl that serve static files and handle comment fetch/add requests.

## Use cases
- learn React basics by following the official tutorial
- run a minimal React example locally
- see how a React frontend talks to a simple comments API
- compare simple server implementations across languages
- get a starting point for a first React app

## When to choose
- you are following the classic React tutorial and want the exact example code
- you want a tiny, dependency-light React demo to run locally

## When to avoid
- you need a modern React setup with hooks, JSX tooling, or a build system
- you want a maintained starter template or production boilerplate
- you need current React best practices - this code is from an older tutorial era

## Facets
- artifact type: learning-resource

- function: web-framework, http-server, developer-tools
- domain: web-development, frontend, tutorials, education
