Question

It was my understanding that $() whas a shortcut alias to jQuery() but then I read this iterator. Are they two different objects then?

EDIT: thanks for the replies. Why is there no consistency in the documentation, which uses $() for the most part then switches to jQuery() in the Utilites section? That’s what made me confused.

Answer 1

No, you were right. They’re aliases. What that doc was trying to say there is that selecting something then iterating over the jQuery wrapper that results:

$(something).each(function() {...});

is a different function to the one on the bare object (whether you call it $ or jQuery:

$.each(something, function() {...});

which can be applied to any sufficiently array-like sequence, not just jQuery wrapper objects.
