如何在这个React JS组件中隐藏setTimeout id？

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.timeoutId = null;
  }

  componentDidMount() {
    this.timeoutId = setTimeout(() => {
      // 定时器逻辑
    }, 1000);
  }

  componentWillUnmount() {
    clearTimeout(this.timeoutId);
  }

  render() {
    return (
      // 组件的渲染逻辑
    );
  }
}

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.timeoutRef = React.createRef();
  }

  componentDidMount() {
    this.timeoutRef.current = setTimeout(() => {
      // 定时器逻辑
    }, 1000);
  }

  componentWillUnmount() {
    clearTimeout(this.timeoutRef.current);
  }

  render() {
    return (
      // 组件的渲染逻辑
    );
  }
}
