cheaper to use array or $$()

[Michael Duff]

Hey Everyone,

I have a question about coding style, I will be using the same "items"
over and over throughout a class I am writing, so would it be better
to place these items in an array for later use?


$$('.someclass').each(function(item, index) {
        this.items[] = item;
});


then anytime I need to loop through them I can just use this.items
instead of $$, does anyone know if its more expensive to store
references to those items or for mootools to go find them each time?
