As your UI grows, you will start repeating the same styles.

Instead of duplicating them, you can reuse styles to keep your code clean and consistent.

Example:

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

export default function App() {
  return (
    <View style={styles.container}>
      <Text style={styles.text}>First item</Text>
      <Text style={styles.text}>Second item</Text>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    padding: 20
  },
  text: {
    fontSize: 16,
    marginBottom: 10
  }
});

Here, the same text style is applied to multiple elements.

You can also combine styles:

const styles = StyleSheet.create({
  text: {
    fontSize: 16
  },
  bold: {
    fontWeight: 'bold'
  }
});

Usage:

<Text style={[styles.text, styles.bold]}>Important</Text>

This lets you build flexible and reusable UI patterns.

Reusing styles helps:

• Keep your code consistent;
• Reduce duplication;
• Make changes easier.
