React Handbook

3/9/2026

• Search no longer depends on letter case: "UseState" finds useState.
• The app is about React again — one handbook, nothing else.
• Fresh react.dev documentation: 177 articles, fully translated into Russian.
• Support for older devices is back — the app runs on Android 5.1 and up again.
• Eight languages: English, Russian, Spanish, French, Portuguese, Japanese, Korean and Chinese.
• Push notifications and analytics removed: the only permission left is internet, for links out.
