Regarding mobile phones — how closely have you worked with React Native? Tell about your experience.

I have worked with React Native on several projects, where I developed cross-platform mobile applications for iOS and Android. My experience includes:

• Developing UI using React Native components and custom styles.
• Integrating with native modules for camera access, geolocation, and other device features.
• Optimizing performance, including using FlatList, component memoization.
• Setting up navigation with React Navigation.
• Debugging and testing on real devices and emulators.

An example of a simple React Native component:

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

const Greeting = ({ name }) => (
  <View style={styles.container}>
    <Text style={styles.text}>Hello, {name}!</Text>
  </View>
);

const styles = StyleSheet.create({
  container: { padding: 16, backgroundColor: '#f0f0f0' },
  text: { fontSize: 18, color: '#333' },
});

export default Greeting;

This experience allows creating user-friendly and high-performance mobile applications using a single codebase for both platforms.
