                    (fn [f]
                      (switch-state! a :waiting :loading)
                      ;; some heavy processing
                      (js/setTimeout (fn [e] (switch-state! :loading :done)) 10000)))
        (add-state [:done :error]
                   {:in (fn []
                          (js/setTimeout #(switch-state! a :done :waiting) 100))
                    :out (fn []
                          (.log js/console "Reset actor to waiting"))})))

Watch state

To add watcher

(watch-state! example-actor :done
    {:in (fn [key]
             (.log js/console "Done!")
     :out (fn [key]
              (.log js/console "Next!"))
