Of course we all know that reading from a simple array is performed by specifying the element number(s), so if we look at the following example:
$array = "apple", "banana", "orange", "plum"
The first element in the array is '0' so:
Write-Host $array[0]
apple
The third element, therefore is '2' so:
Write-Host $array[2]
orange
Very easy, but a lesser known trick is to count from the last element backwards. The last element of an array is '-1' and so forth...
Write-Host $array[-1]
plum
Write-Host $array[-2]
orange
This is useful, without this you would have to do something like this:
Write-Host $array[$array.length - 1]
plum
Write-Host $array[$array.length - 2]
orange
Cheers!
