This example demonstrates how to implement a simple counter using the useState hook in React Native:

// Example of useState hook in React Native

import React, { useState } from 'react';

import { View, Text, Button } from 'react-native';

function Counter() {

  const [count, setCount] = useState(0);

  

  return (

    <View>

      <Text>You clicked {count} times</Text>

      <Button title="Click me" onPress={() => setCount(count + 1)} />

    </View>

  );

}

Employing JavaScript alongside JSX syntax, which are second nature to those familiar with React, simplifies mobile app creation while maintaining high performance through native APIs. This seamless integration between React and its mobile counterpart enables web developers to transition into mobile application development effortlessly, without needing to tackle an entirely new framework.

const BasicComponentsDemo = () => {

  return (

    <View style={styles.container}>

      <Text style={styles.title}>Hello React Native</Text>

      <Image

        source={{ uri: 'https://reactnative.dev/img/tiny_logo.png' }}

        style={{ width: 100, height: 100 }}

      />

    </View>

  );

};

const styles = StyleSheet.create({

  container: { padding: 20, alignItems: 'center' },

  title: { fontSize: 24, fontWeight: 'bold' },

});

React Native empowers developers to create apps for both iOS and Android using a single JavaScript codebase. It achieves this through universal components like `View`, `Text`, and `Image`, which seamlessly connect to native UI elements on each platform. When specific platform logic is required, developers can utilize the `Platform` module or employ conditional rendering.

This code shows how to implement platform-specific UI elements and styles:

// Platform-specific code example

import React from 'react';

import { View, Text, Platform } from 'react-native';

const PlatformExample = () => (

  <View>

    {/* Conditional rendering based on platform */}

    <Text>

      {Platform.OS === 'ios' ? 'Running on iOS' : 'Running on Android'}

    </Text>

    

    {/* Platform-specific styles */}

    <View style={{

      borderRadius: Platform.OS === 'ios' ? 10 : 4,

      ...Platform.select({

        ios: { shadowOpacity: 0.2 },

        android: { elevation: 4 },

      })

    }}>

      <Text>Platform-specific styling</Text>

    </View>

  </View>

);

The framework enhances code reusability by employing React’s component-based architecture. This allows mobile projects to share business logic, styling, and some native modules across different platforms. Consequently, it reduces development time and eases maintenance while ensuring a unified user experience.

When direct engagement with native features is essential, React Native supports writing platform-specific code in languages such as Java, Kotlin, Swift, or Objective-C.
