10React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components. With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C or Java.

84## Key Recommendations
85
86- **Use StyleSheet.create()** for all styles instead of inline objects
87- **Use FlatList** instead of ScrollView for long lists
88- **Enable useNativeDriver** for animations when possible (transform, opacity)
89- **Use Pressable** for new touch interactions (preferred over Touchable components)
90- **Handle platform differences** with Platform.select() and Platform.OS
91- **Test on real devices** - simulator behavior may differ from actual devices
92- **Optimize list performance** with getItemLayout for fixed-height items
93- **Use TypeScript** for better type safety and developer experience
