当我使用React Js按下按钮时，如何将旧的数组列表键动态递增5倍？

import React, { useState } from 'react';

function MyComponent() {
  const [list, setList] = useState([]);

  const handleButtonClick = () => {
    // 将旧的数组列表键动态递增5倍
    const newList = list.map(item => item * 5);
    setList(newList);
  };

  return (
    <div>
      <button onClick={handleButtonClick}>点击按钮</button>
      <ul>
        {list.map(item => <li key={item}>{item}</li>)}
      </ul>
    </div>
  );
}

export default MyComponent;
