Resets an array to a specified minimum number of elements. ArrayResize can provide some performance gains if used to size an array to its expected maximum. For arrays greater than 500 elements, use ArrayResize immediately after creating an array with ArrayNew.
ColdFusion arrays expand dynamically as data is added.
Returns a Boolean TRUE on successful completion.
