如何将this.state放入一个状态改变后不会改变的变量中？

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      count: 0
    };
  }

  handleClick() {
    this.setState({ count: this.state.count + 1 }, () => {
      const updatedCount = this.state.count; // 在回调函数中获取更新后的状态值
      console.log(updatedCount); // 输出更新后的状态值
    });
  }

  render() {
    return (
      <div>
        <button onClick={() => this.handleClick()}>增加</button>
      </div>
    );
  }
}
