Two good jQuery links for the Christmas season:
1. A fantastic â€˜Improve your jQuery â€“ 25 excellent tipsâ€™ by Jon Hobbs-Smith â€“ and these are excellent tips!
I found the internal â€˜dataâ€™ method to store state to be interesting â€“ as well as the idea of using classes to store state â€“ very cool approach!
Have a Merry Christmas!
