如何将类组件中的嵌套状态更改为功能组件中的状态？

import React, { useState } from 'react';

// 原来的类组件
class MyClassComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      count: 0,
    };
  }

  incrementCount() {
    this.setState((prevState) => ({
      count: prevState.count + 1,
    }));
  }

  render() {
    return (
      <div>
        <p>Count: {this.state.count}</p>
        <button onClick={() => this.incrementCount()}>Increment</button>
      </div>
    );
  }
}

// 新的函数组件
function MyFunctionComponent() {
  const [count, setCount] = useState(0);

  function incrementCount() {
    setCount((prevCount) => prevCount + 1);
  }

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={incrementCount}>Increment</button>
    </div>
  );
}

// 使用新的函数组件
function App() {
  return <MyFunctionComponent />;
}
