如何将我的数组拆分为10个元素的小数组，并每次移位2个元素？

function splitArray(array) {
  var result = [];
  var length = array.length;
  
  for (var i = 0; i < length; i += 2) {
    var temp = array.slice(i, i + 10);
    result.push(temp);
    
    // 移位2个元素
    array.push(array.shift());
    array.push(array.shift());
  }
  
  return result;
}

// 示例用法
var myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20];
var splitResult = splitArray(myArray);
console.log(splitResult);

[
  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  [3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
  [5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
  [7, 8, 9, 10, 11, 12, 13, 14, 15, 16],
  [9, 10, 11, 12, 13, 14, 15, 16, 17, 18],
  [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]
]
