T.J. $$W and $$ are the same thing (just named $$W so that we know we are talking about the new implementation).
I kind of like the idea of lazy wrapping. That would speed up the initial selector while offering a one time hit later on, on only the elements chosen (which is usually all of them being iterated over by "each" or "include") but for those cases were it iterates against "find" it would help because the un-iterated items wont be wrapped. Wrapping is by no means as slow as extending the elements manually (ala IE), you create an instance and assign it the passed element so the speed hit is still minimal. Having to iterate over a list of matches elements is just another hit to performance. By using lazy wrapping we can avoid that and keep it as streamline and as few steps between the native selector methods as possible. $$(css).each(...); $$(css).item(2).addClassName('awesome'); The $$(...)._each would iterate over the internal list so it wouldn’t need to call item(i) during its iterations. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype: Core" group.
