Understanding React Native Performance
Performance is critical for mobile apps. Let's explore key optimization techniques.
Key Optimization Techniques
1. Use FlatList for Long Lists
import { FlatList } from 'react-native';
const MyList = ({ data }) => (
<FlatList
data={data}
renderItem={({ item }) => <ListItem item={item} />}
keyExtractor={(item) => item.id}
initialNumToRender={10}
maxToRenderPerBatch={5}
windowSize={5}
/>
);2. Memoize Components
import React, { memo } from 'react';
const ExpensiveComponent = memo(({ data }) => {
// Complex rendering logic
return <View>...</View>;
});Always profile your app before and after optimizations to measure impact.
Conclusion
Performance optimization is an ongoing process. Monitor, measure, and iterate.
