获取数组的每四个数组，并在

// 定义一个数组
const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16];

// 循环遍历数组
for (let i = 0; i < array.length; i += 4) {
  // 获取当前四个元素
  const subArray = array.slice(i, i + 4);

  // 打印当前四个元素
  console.log(subArray);
}

[1, 2, 3, 4]
[5, 6, 7, 8]
[9, 10, 11, 12]
[13, 14, 15, 16]
