[System.Collections.ArrayList]$array = @("first", "second", "third", "fourth")

$array

$arrayBefore = $array #this creates connection - when removed from array, removed also from arrayBefore

$nextArray = $array.Clone() #creates copy without connection

$array.RemoveAt(2)

$array.Remove("fourth")

$array.IndexOf("first")

"`nArray"
