按字符串值对数组进行排序，如果值以数字开头，则使用特殊排序

function customSort(arr) {
  arr.sort(function(a, b) {
    var isANumber = /^\d/.test(a);
    var isBNumber = /^\d/.test(b);

    if (isANumber && isBNumber) {
      return parseInt(a) - parseInt(b);
    } else if (isANumber) {
      return -1;
    } else if (isBNumber) {
      return 1;
    } else {
      return a.localeCompare(b);
    }
  });

  return arr;
}

// 示例用法
var array = ["2abc", "1def", "xyz", "10ghi", "3jkl"];
var sortedArray = customSort(array);
console.log(sortedArray);
