实用小函数

数组随机化

    const fn1 = (arrlist) => {
      arrlist.sort(() => Math.random() - 0.5);
      return arrlist;
    };
    let arr = [1, 2, 3, 4, 5];
    console.log(fn1(arr), "fn1(arr)");

获取随机十六进制颜色

const generateRandomHexColor = () =>
  `#${Math.floor(Math.random() * 0xffffff).toString(16)}`;
