[VBScript] Map. Is there a more useless function?

Map is great for other languages. I've implemented it for no good reason. And I really can't think of a good use for it. Anyone? function map( arrSource, strOp ) Dim i Dim varItem Dim strEval Dim max Dim arrCopy arrCopy = arrSource max = UBound( arrCopy ) For i = 0 To max varItem = arrCopy( i ) strEval = Replace( strOp, "${item}", varItem ) arrCopy( i ) = Eval( strEval ) Next map = arrCopy End Function dim arr arr = map ( array(1,2,3,4,5,6,7,8,9),"${item}*${item}" ) 'arr now equals array(1,4,9,16,25,36,49,64,81)
