If you're really worried about the efficiency you shouldn't use
removeItemAt, but rather just call:
states.splice( index, 1 );
That will delete a single element at a specified index. Then, when
you're done deleting all elements, you'll want to dispatch a
modelChanged event so that all of the listening elements to the data
provider get updated:
states.dispatchEvent({type:"modelChanged"});
Doing it the above way will avoid the modelChanged event being
dispatched for every element removal, avoiding all of that extra
processing. Rather, you can "batch" your changes via splice then notify
all of the listeners at the end.
And yes, looping over the elements backwards would be slightly faster
than subtracting i again each iteration..
