1. Use FlashList instead of FlatList
Shopify's FlashList recycles views much more efficiently than the standard FlatList, crucial for long lists of data.
2. Memoization
Prevent unnecessary re-renders of child components by using React.memo and useCallback.
jsx
const MyItem = React.memo(({ title }) => {
return <Text>{title}</Text>;
});
