## What it is
A simple React tutorial consisting of browser-runnable HTML lesson files that teach React fundamentals without build tooling or ES2015 syntax. It covers elements, JSX, components, and properties through a series of small, self-contained examples.

## Use cases
- learn React basics from scratch
- understand JSX without a build setup
- run React examples directly in the browser
- teach React fundamentals in a workshop
- review core React concepts like components and props

## When to choose
- you are a beginner wanting minimal, no-tooling React lessons
- you want to understand React fundamentals without ES2015 syntax
- you need self-contained examples that run in any browser

## When to avoid
- you need modern JavaScript (ES2015+) and hooks-based React
- you want a full course with state management, routing, or testing
- you need actively maintained material for current React versions

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: frontend, web-development, tutorials
- platform: browser
- tags: react, tutorial, lessons, jsx, self-contained-examples, beginner, web-server
