On: Again on 0-based vs. 1-based indexing

[tester34]

because when you misscalculate the index, then it will not crash, but use the wrong one

I'm getting this right?

I don't understand why that would be more error prone than using list[list.length-1]. It's just list[-1].

[tester34 → robertlagrant]

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
