sounds like a great way to introduce bugs

  How so?

    because when you misscalculate the index, then it will not crash, but use the wrong one I'm getting this right?
    • robertlagrant 6y ago
      I don't understand why that would be more error prone than using list[list.length-1]. It's just list[-1].
      • tester34 6y ago
        imagine if you used list[index] where index would be calculated if you misscalculated something and went on negative, then you'd have big exception/error, but when negative indices are viable, then the code will work fine
