Global jQuery view, yes? I stand by a slightly statement that what is common and needs to be fast for Yehuda may not be common and needing to be fast in general.
In particular, lots of jQuery selector usage is not in fact performance-sensitive. Some obviously is. Again, I'd love to see data on the cases where performance matters, both when jQuery is involved and when it's not.
I should note that the larger and more complicated a web app the less likely it is to use jQuery from what I've seen....
I'm absolutely sure that simple selectors dominate complicated ones in all contexts, but again I'd really like to have data on what _sort_ of simple selectors really need optimizing.
The jQuery team did look to see what selector are "hottest" against their engine
Yes. See above. -Boris
