我正在尝试将此React类组件更改为功能组件

// 类组件
class MyComponent 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>
    );
  }
}

// 功能组件
const MyComponent = () => {
  const [count, setCount] = React.useState(0);

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

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