What is the point of the negative indices? It’s called “negative” and says to reference items in reverse order but you only get the last item in the array. Can someone help me make sense of this?

Below I used the range operator:

PS C:\Users\Mr> $food[-1..-$food.Count]
PS C:\Users\Mr> 

Couldn’t you use the reverse indices for this tho?

I didn’t take up enough reading to try that. Please demonstrate. There doesn’t seem to be a lesson checker on that module so I quit taking the course.

I mean if you do something like this:

PS > $food[5..0]

You would get the same result. All listed in reverse order.
Is this negative indices thing maybe more for when you don’t know how long the array is?

In a dynamic case we have nothing but the program to help determine array size, in which case I would answer, yes.
