[solved]Diff Two Arrays help plz

#1

I don’t understand why this is working for the first 5 tests but not the last three. Could someone please explain the issue?

function diffArray(arr1, arr2) {
  var newArr = [];

  for (var i = 0; i < arr1.length && i < arr2.length; i++)
    if (arr2.indexOf(arr1[i]) == -1) {
      newArr.push(arr1[i]);
    }
  else if (arr1.indexOf(arr2[i]) == -1) {
      newArr.push(arr2[i]);
    }
   return newArr;

}


diffArray([1, "calf", 3, "piglet"], [7, "filly"]);
