Ruby on Rails way of managing views

Hi RoR experts,

I have a really small question which is probably depends on a personal
taste but I want to know your opinion.
I was told that RoR is widely used to render erb files and allows to
deliver things faster however I do know about the dark side of using the
rails api and some js framework like ember. You might remember my asking
the question about your preferred js framework, however js is a matter
of taste.

So, one more time. The main question : is it still the case that erb
could give some advantage in app support or delivery time over the rails
api with some js framework? What is your opinion on this?

The question is meaningless, unless I misunderstand what you are
asking, erb is a server side technology and js is client side. Most
non-trivial sites require both.
