如何修复比onClick事件晚一步状态更改问题

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

  handleClick() {
    this.setState({ count: this.state.count + 1 }, () => {
      console.log('状态已更新');
      // 在这里进行状态更新后的操作
    });
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick.bind(this)}>点击我</button>
        <p>当前计数：{this.state.count}</p>
      </div>
    );
  }
}

import React, { useState, useEffect } from 'react';

function MyComponent() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    console.log('状态已更新');
    // 在这里进行状态更新后的操作
  }, [count]);

  const handleClick = () => {
    setCount(count + 1);
  };

  return (
    <div>
      <button onClick={handleClick}>点击我</button>
      <p>当前计数：{count}</p>
    </div>
  );
}
