React Native: What is the difference between functional and class components in React Native?

1// Functional component
2function App() {
3    const [count, setCount] = useState(0);
4
5    return (
6        <View>
7            <Text>{count}</Text>
8            <Button onPress={() => setCount(count + 1)} />
9        </View>
10    );
11}

1// Class component
2class App extends React.Component {
3    constructor(props) {
4        super(props);
5        this.state = { count: 0 };
6    }
7
8    render() {
9        return (
10            <View>
11                <Text>{this.state.count}</Text>
12                <Button onPress={() => this.setState({ count: this.state.count + 1 })} />
13            </View>
14        );
15    }
16}
