Reagent means you don't have to grok Reagent at all. If you know how Clojure atoms work, how to use Hiccup-style templates, and understand that all templates ('components') that dereference a Reagent atom will be automatically updated when the atom is, then you know how to use Reagent.

I think you meant "grok React". But yes, Reagent is super-nice. I'm surprised much of the community has gone for Om, since Reagent strikes me as much cleaner 98% of the time. Om maps closely to React, when most of the time it doesn't have to.
