将JSON数组设置为state，不显示propper javascript对象

import React, { useState } from 'react';

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

  // 其他组件逻辑...

  return (
    // JSX代码...
  );
}

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

  return (
    <div>
      {data.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
}

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

  const addNewItem = () => {
    const newItem = { id: 4, name: 'Alice' };
    setData(prevData => [...prevData, newItem]);
  };

  return (
    <div>
      {data.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
      <button onClick={addNewItem}>Add Item</button>
    </div>
  );
}
