ClojureScript to Javascript : how to return nothing

Question

I am using ClojureScript in an interoperability scenario, and I have a public function that is basically a go block. When I call it from my browser console, it returns a ClojureScript object (the result of go).

I would like to return nothing not even undefined (as in return;). How do I do that ?

(defn :^export myFn [cb]
  (go ...)
  js/undefined) ;; what do I put here instead of js/undfined?

In Javascript a return; will return undefined:

(typeof (function() {return;})())
=> "undefined"

Hence your js/undefined is just fine.
