如何在react中输出字符串状态值？

import React, { useState } from 'react';

function MyComponent() {
  const [stringValue, setStringValue] = useState('Hello');

  // 其他组件逻辑...

  return (
    <div>
      {stringValue}
    </div>
  );
}

return (
  <div>
    {stringValue}
  </div>
);

function handleClick() {
  setStringValue('New Value');
}

return (
  <div>
    {stringValue}
    <button onClick={handleClick}>Update Value</button>
  </div>
);
