View          - Container component (like div)
Text          - Text display (required for strings)
Image         - Image rendering
ScrollView    - Scrollable container
FlatList      - Optimized list rendering
TextInput     - User input

// StyleSheet.create for performance
const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    padding: 16,
  },
  title: {
    fontSize: 24,
    fontWeight: 'bold',
    color: '#1a1a1a',
  },
});

// Common patterns
flexDirection: 'row' | 'column'     // Main axis
justifyContent: 'center' | 'space-between'  // Main axis alignment
alignItems: 'center' | 'stretch'    // Cross axis alignment
flex: 1                              // Grow to fill

import { Platform } from 'react-native';

// Method 1: Platform.select
const styles = StyleSheet.create({
  shadow: Platform.select({
    ios: { shadowColor: '#000', shadowOpacity: 0.1 },
    android: { elevation: 4 },
  }),
});

// Method 2: Platform.OS
if (Platform.OS === 'ios') {
  // iOS specific code
}
