谁能给出一个更真实的例子，说明setState(updaterFunc)函数比setState(object)函数更有用？

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

  increment() {
    this.setState((prevState) => {
      return {
        count: prevState.count + 1
      };
    });
  }

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

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

  increment() {
    this.setState({ count: this.state.count + 1 });
  }

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