The accepted answer wasn't working for me with the javascript object window.performance.timing. This is because Object.keys() doesn't actually return the props for the PerformanceTiming object.

(.keys js/Object (.-timing (.-performance js/window))
; => #js[]

This is despite the fact that the props of PerformanceTiming are indeed iterable with a vanilla JavaScript loop:

for (a in window.performance.timing) {
 console.log(a);
}
// navigationStart
// unloadEventStart
// unloadEventEnd
// ...

The following is what I came up with to convert an arbitrary JavaScript object to a ClojureScript map. Note the use of two simple Google Closure functions.

• goog.typeOf wraps typeof, which isn't normally accessible to us in ClojureScript. I use this to filter out props which are functions.
• goog.object.getKeys wraps for (prop in obj) {...}, building up an array result which we can reduce into a map.

#Solution (flat)

(defn obj->clj
 [obj]
 (-> (fn [result key]
 (let [v (goog.object/get obj key)]
 (if (= "function" (goog/typeOf v))
 result
 (assoc result key v))))
 (reduce {} (.getKeys goog/object obj))))

Solution (recursive)

Update: This solution will work for nested maps.

(defn obj->clj
 [obj]
 (if (goog.isObject obj)
 (-> (fn [result key]
 (let [v (goog.object/get obj key)]
 (if (= "function" (goog/typeOf v))
 result
 (assoc result key (obj->clj v)))))
 (reduce {} (.getKeys goog/object obj)))
 obj))
