JS冒泡排序---数组从小到大排列

const arr = [23, 34, 14, 56, 334, 26, 12, 6];
//[23,14,34,56,26,12,6,334]
//[14,23,34,36,12,6,56,334]
//[14,23,34,12,6,36,56,334]
//[14,23,12,6,34,36,56,334]
//[14,12,6,23,34,36,56,334]
//[12,6,14,23,34,36,56,334]
//[6,12,14,23,34,36,56,334]
for (let i = 0; i < arr.length - 1; i++) {
  for (let index = 0; index < arr.length - 1 - i; index++) {
    if (arr[index] > arr[index + 1]) {
      let num = arr[index]; //保存最大数
      arr[index] = arr[index + 1]; //让最大数所在位置变成最小数
      arr[index + 1] = num; //让最小数所在位置变成最大数(已保存了最大数)
    }
  }
