What Is React Native?
React Native Framework
React Native lets you build native mobile apps for iOS and Android using React and JavaScript. It renders actual native UI components (not web views), so apps feel native while sharing most code across platforms. Facebook, Instagram, and Shopify use React Native.
How React Native Works
If you know React, you already know most of React Native. Components like View, Text, and TouchableOpacity replace HTML elements. Styles use a flexbox-based system. Expo simplifies setup, builds, and deployment — it's the recommended way to start.
React Native's 'New Architecture' (Fabric renderer, TurboModules) dramatically improves performance and reduces the bridge overhead that was historically its weakness. With Expo and the new architecture, React Native is a strong choice for cross-platform development.
Why Developers Use React Native
React Native is ideal for teams with React/JavaScript expertise who need mobile apps. It shares code between platforms and with web (React). It's the practical choice when you want native mobile presence without learning Swift and Kotlin separately.
Key Concepts
- Native Components — React Native renders actual platform UI components — UIKit on iOS, Android Views on Android
- Expo — A framework and platform that simplifies React Native development — handles builds, updates, and device APIs
- Bridge/New Architecture — The system connecting JavaScript to native code — the new architecture eliminates the bridge for better performance
- Code Sharing — Share business logic, utilities, and sometimes components between React Native mobile and React web apps

Frequently Asked Questions
React Native vs Flutter?
React Native if your team knows JavaScript/React. Flutter if you want the best cross-platform UI consistency and are willing to learn Dart. Both are production-ready.
Is React Native truly native?
It renders native UI components and has access to native APIs. Performance is near-native for most apps. CPU-intensive work (games, video processing) may need native modules.
