You can optimize performance in a React Native app by using techniques such as memoization, avoiding unnecessary re-renders, and optimizing list rendering with FlatList.
Solution Code
React Native
-- Example Code --
import React, { useMemo } from "react";
import { View, Text } from "react-native";
const App = () => {
const data = useMemo(() => {
// Perform some complex calculation here
return [1, 2, 3, 4, 5];
}, []);
return (
<View>
<Text>{data.join(", ")}</Text>
</View>
);
};
export default App;Explanation
This code demonstrates how to use memoization to optimize performance.Guided Hints
