## What it is
A free open-source book covering design patterns and techniques used while developing with React, available in web, PDF, Mobi, and ePub formats. It includes runnable code samples and covers topics like composition, higher-order components, one-directional data flow, Flux, Redux, dependency injection, and styling approaches.

## Use cases

- you are learning React fundamentals like composition and data flow
- you prefer books with accompanying runnable code samples

## When to avoid
- you need up-to-date coverage of the latest React features like server components
- you want an interactive course or video tutorials instead of a book
- you need a reference for a specific React library's API

## Facets
