When would i use angular 2 over jquery

Thanks for your reply.

It does make sense but wouldn’t it be best to do away with jquery and use angualr.

e,g say i have a pretty standard site, 3-4 pages, home page slider, contact form. What i understand is i can do the slider and the form validation all in angular without jquery (obviously i could just do it in vanilla js). would that be a good idea?

Does anyone have any examples of sites built in angular?
