Is posible replace jsf or jsp for angularjs framework?

Question

one of my friends told me that jsf will be deprecated in favor of angularjd

Answer 1

Yes. It can be done.

Angular, React, Polymer are frontend frameworks. So, they'll work flawlessly if you feed them necessary data from api.

And, you can develop api's using any backend platform like, node, rails, java, c# etc.
