如何在React Native中使用数据调用变量

import React, { useState } from 'react';
import { View, Text } from 'react-native';

const App = () => {
  const [data, setData] = useState('Hello World');
  
  // 其他代码...
}

const App = () => {
  const [data, setData] = useState('Hello World');
  
  return (
    <View>
      <Text>{data}</Text>
    </View>
  );
}

const App = () => {
  const [data, setData] = useState('Hello World');
  
  const updateData = () => {
    setData('New Value');
  }
  
  return (
    <View>
      <Text>{data}</Text>
      <Button title="Update" onPress={updateData} />
    </View>
  );
}
