Then, access them in the documented way: divs.eq(0). If brackets work now, as they are not mentioned in the documentation then, no, you can't count on that working in the future. Nathan
Actually, I'm going to go out on a limb and say that you can count on the array notation staying in jQuery.
By the way, divs.get(0) and divs[0] return the DOM node, but divs.eq(0) still returns the jQuery object. Also, jQuery is not an array at heart, but an array-like object.
