React:更新处于状态的对象数组的正确方法

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      items: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' }
      ]
    };
  }

  updateItemName = (itemId, newName) => {
    this.setState(prevState => ({
      items: prevState.items.map(item => {
        if (item.id === itemId) {
          return { ...item, name: newName };
        }
        return item;
      })
    }));
  };

  render() {
    return (
      <div>
        {this.state.items.map(item => (
          <div key={item.id}>
            {item.name}
            <button onClick={() => this.updateItemName(item.id, 'New Name')}>
              Update Name
            </button>
          </div>
        ))}
      </div>
    );
  }
}

export default MyComponent;
