Display a header with the title 'Turbo Modules Overview'

Show a short paragraph explaining what Turbo Modules are

List at least three benefits of Turbo Modules as bullet points

Use basic React Native components like View, Text, and ScrollView

Make sure the text is readable and spaced nicely

Starter Code

React Native

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

export default function TurboModulesInfo() {
  return (
    <ScrollView contentContainerStyle={styles.container}>
      {/* TODO: Add header title here */}
      {/* TODO: Add explanation paragraph here */}
      {/* TODO: Add benefits list here */}
    </ScrollView>
  );
}

const styles = StyleSheet.create({
  container: {
    padding: 20,
    backgroundColor: '#fff'
  }
});

Solution

React Native

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

export default function TurboModulesInfo() {
  return (
    <ScrollView contentContainerStyle={styles.container}>
      <Text style={styles.header}>Turbo Modules Overview</Text>
      <Text style={styles.paragraph}>
        Turbo Modules are a new architecture in React Native that allow faster native module loading and better performance.
      </Text>
      <Text style={styles.subheader}>Benefits:</Text>
      <View style={styles.list}>
        <Text style={styles.listItem}>• Async initialization</Text>
        <Text style={styles.listItem}>• Reduced bridge overhead</Text>
        <Text style={styles.listItem}>• Easier native code updates</Text>
      </View>
    </ScrollView>
  );
}

const styles = StyleSheet.create({
  container: {
    padding: 20,
    backgroundColor: '#fff'
  },
  header: {
    fontSize: 24,
    fontWeight: 'bold',
    marginBottom: 15
  },
  paragraph: {
    fontSize: 16,
    marginBottom: 20
  },
  subheader: {
    fontSize: 18,
    fontWeight: '600',
    marginBottom: 10
  },
  list: {
    paddingLeft: 10
  },
  listItem: {
    fontSize: 16,
    marginBottom: 8
  }
});

This screen uses a ScrollView to allow vertical scrolling if needed. The header uses a larger bold font to stand out. The paragraph explains Turbo Modules simply. The benefits are shown as bullet points using separate Text components with a dot character. Spacing and font sizes are chosen for easy reading on mobile screens.

User can scroll vertically if content is longer than screen

Text is static with no interactive elements

Stretch Goal

Add a dark mode toggle that switches the background and text colors

💡 Hint

Use React state to track dark mode on/off and conditionally apply styles
