what to choose Jquery or Closure?
i have some basic (superficial) knowledge of `Jquery` and was thinking of learning it. Recently i have been hearing of `Closure library` by Google that has features like `namespaces` and can be `compiled` (optimized) and produces high performance javascript. Jquery is said to be very good at creating `interactive applications` and handling `cross browser issues`. Is closure that good at doing what Jquery can do? If i have to `choose one of them` for learning and then using it, which one should i choose?
