Clojurians Log v2

I came across this macro:

(defmacro js-for
  "Like for, but efficiently builds up a js array."
  {:style/indent 1}
  [binding body]
  `(let [^js arr# (js/Array.)]
     (doseq ~binding (.push arr# ~body))
     arr#))

Don't look at the implementation. What I'm just interested in here. When evaluating this macro, the arr# symbol has tag user/js. Is this accepted by the CLJS compiler as a hint or not (as opposed to just js). I don't think the hint is necessary here, but ok.
