You could get the end result of a lot of these smaller example applications with jquery but making anything bigger is going to get very unmanageable very quickly. Also considering how close angular 2 is to react I'd be surprised if by learning one you wouldn't be able to at least understand code in the other. I guess it really depends what your end goal is.
