I cut my teeth using Ember a few years back, the whole community is amazing and does great work. Using react/redux now, and while I think it's the simplest and most pragmatic approach (the connect function changed the game), I think the api's over in clojurescript land, specifically re-frame are the best . It's conceptually the same as react/redux, but with a few more facilities for isolating side effects in actions, and a wayyyyy simpler api for querying the store in functional components.

But what I came to say is I think templating languages are sub par. Using an actual programming language that returns "html", or some variant (like clojurescripts hiccup language) is way more useful. I wouldn't use this because of that.
