- Code reusability across iOS and Android (typically 70-90%)
- Faster development cycle compared to native development
- Hot reloading for quick iterations
- Large community and ecosystem
- Backed by Facebook with active maintenance
- Access to native APIs through bridge or native modules
Disadvantages:
- Performance overhead due to bridge communication
- Limited access to latest native features immediately

Core components are the essential building blocks provided by React Native:
- View: Container component similar to
divin HTML - Text: For displaying text content
- Image: For displaying images
- ScrollView: Scrollable container
- TextInput: For user text input
- TouchableOpacity/TouchableHighlight: For handling touch events
- FlatList/SectionList: For rendering lists efficiently
- Switch: Toggle switch component
- ActivityIndicator: Loading spinner
import { View, Text, Image, TouchableOpacity } from 'react-native';
const MyComponent = () => (
<View>
<Text>Hello World</Text>
<TouchableOpacity onPress={() => console.log('Pressed')}>
<Text>Press me</Text>
</TouchableOpacity>
</View>
);

- View: Basic container component that doesn't account for device-specific safe areas
- SafeAreaView: Automatically adjusts content to avoid system UI elements like status bars, notches, and home indicators
// Without SafeAreaView - content might be hidden behind status bar
<View style={{flex: 1}}>
<Text>This might be hidden</Text>
</View>
// With SafeAreaView - content stays within safe boundaries
<SafeAreaView style={{flex: 1}}>
<Text>This is always visible</Text>
</SafeAreaView>

Props (Properties):
- Data passed from parent to child components
- Immutable within the receiving component
- Used for component configuration and data flow
State:
- Internal component data that can change over time
- Mutable using useState or setState
- Triggers re-renders when updated
// Props example
const ChildComponent = ({title, onPress}) => (
<TouchableOpacity onPress={onPress}>
<Text>{title}</Text>
</TouchableOpacity>
);
// State example
const ParentComponent = () => {
const [count, setCount] = useState(0);
return (
<ChildComponent
title={`Count: ${count}`}
onPress={() => setCount(count + 1)}
/>
);
};

React Navigation is the most popular navigation library for React Native. It provides:
- Stack Navigation: Screen transitions with a stack-like structure
- Tab Navigation: Bottom or top tab bars
- Drawer Navigation: Side menu navigation
- Native Performance: Smooth animations and gestures
- Customization: Extensive theming and configuration options
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
const Stack = createStackNavigator();
const App = () => (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={HomeScreen} />
<Stack.Screen name="Profile" component={ProfileScreen} />
</Stack.Navigator>
</NavigationContainer>
);

Use the navigate function with parameters and access them via the route prop:
// Passing parameters
const HomeScreen = ({navigation}) => {
const navigateToProfile = () => {
navigation.navigate('Profile', {
userId: 123,
userName: 'John Doe'
});
};
return (
<TouchableOpacity onPress={navigateToProfile}>
<Text>Go to Profile</Text>
</TouchableOpacity>
);
};
// Receiving parameters
const ProfileScreen = ({route}) => {
const {userId, userName} = route.params;
return (
<View>
<Text>User ID: {userId}</Text>
<Text>Name: {userName}</Text>
</View>
);
};

React Native uses a subset of CSS properties implemented through JavaScript objects:
import { StyleSheet, View, Text } from 'react-native';
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#f0f0f0',
justifyContent: 'center',
alignItems: 'center',
},
text: {
fontSize: 16,
fontWeight: 'bold',
color: '#333',
}
});
const MyComponent = () => (
<View style={styles.container}>
<Text style={styles.text}>Hello World</Text>
</View>
);
