如何找出具有嵌套数组的两个数组之间的差异

function findArrayDifference(arr1, arr2) {
  var diff = [];

  arr1.forEach(function(element) {
    if (Array.isArray(element)) {
      var nestedDiff = findArrayDifference(element, arr2);
      if (nestedDiff.length > 0) {
        diff.push(nestedDiff);
      }
    } else if (arr2.indexOf(element) === -1) {
      diff.push(element);
    }
  });

  return diff;
}

// 示例用法
var array1 = [1, 2, [3, 4]];
var array2 = [1, [3, 4], 5];

var difference = findArrayDifference(array1, array2);
console.log(difference); // 输出: [2]
