I have an array of objects. I'd like to grab items from the array by
specifying a range like 1-10, or 11-20, or 5-7, and so on..
Seems trivial. How is this done with Prototype?

var arr = $w('the quick brown fox jumped over the lazy dog');
That should work. Was imagining a method off the array object directly.
Thanks.

Well, you can always use the generic Array.slice() method.
$A($w('the quick brown fox jumped over the lazy
dog').slice(1,5)).each(function(elm){console.log(elm);});

Just to point out, the $A( ) wrapper around the slice product was there because
you can't guarantee an extended array in IE without it. Every other browser
would be fine. Also, if you weren't using any Prototype magic on the output
array, you could skip that as well.

No, IE allows Prototype to automagically extend arrays just
automagically
