The useRef hook is used to create a mutable ref object whose current property is initialized to the passed argument. It can be used to access DOM elements or to store any mutable value.
Solution Code
React Native
-- Example Code --
import React, { useRef } from "react";
import { View, Text, Button } from "react-native";
const App = () => {
const countRef = useRef(0);
const increment = () => {
countRef.current += 1;
console.log(countRef.current);
};
return (
<View>
<Text>Count: {countRef.current}</Text>
<Button title="Increment" onPress={increment} />
</View>
);
};
export default App;Explanation
