브라우저 창 크기 조정 시 반응에서 어떻게 다시 렌더링을 트리거할 수 있습니까?

<code class="javascript">import React, { useLayoutEffect, useState } from 'react';

function useWindowSize() {
  const [size, setSize] = useState([0, 0]);
  useLayoutEffect(() => {
    function updateSize() {
      setSize([window.innerWidth, window.innerHeight]);
    }
    window.addEventListener('resize', updateSize);
    updateSize();
    return () => window.removeEventListener('resize', updateSize);
  }, []);
  return size;
}</code>

<code class="javascript">import React from 'react';

class ShowWindowDimensions extends React.Component {
  state = { width: 0, height: 0 };
  render() {
    return (
      <span>
        Window size: {this.state.width} x {this.state.height}
      </span>
    );
  }
  updateDimensions = () => {
    this.setState({
      width: window.innerWidth,
      height: window.innerHeight
    });
  };
  componentDidMount() {
    window.addEventListener('resize', this.updateDimensions);
  }
  componentWillUnmount() {
    window.removeEventListener('resize', this.updateDimensions);
  }
}</code>
