更新数组中对象的值- react挂钩

import React, { useState } from 'react';

const App = () => {
  const [data, setData] = useState([
    { id: 1, name: 'John' },
    { id: 2, name: 'Jane' },
    { id: 3, name: 'Bob' }
  ]);

  const updateName = (id, newName) => {
    const updatedData = data.map(item => {
      if (item.id === id) {
        return { ...item, name: newName };
      }
      return item;
    });

    setData(updatedData);
  };

  return (
    <div>
      {data.map(item => (
        <div key={item.id}>
          <span>{item.name}</span>
          <button onClick={() => updateName(item.id, 'New Name')}>Update Name</button>
        </div>
      ))}
    </div>
  );
};

export default App;
