Source docstring:

Given a string of JavaScript, evaluate it in the browser and return a map representing the
result of the evaluation. The map will contain the keys :type and :value. :type can be
:success, :exception, or :error. :success means that the JavaScript was evaluated without
exception and :value will contain the return value of the evaluation. :exception means that
there was an exception in the browser while evaluating the JavaScript and :value will
contain the error message. :error means that some other error has occured.

(defn browser-eval
  [form]
  (let [return-value (promise)]
    (send-for-eval form
      (fn [val] (deliver return-value val)))
    (let [ret @return-value]
      (try
        (read-string ret)
        (catch Exception e
          {:status :error
           :value (str "Could not read return value: " ret)})))))
