Converting Monstrous JavaScript code to elegant Clojurescript code

Question

I have such terrible JavaScript code

response.items[0].fields.image.fields.file.url

I can convert it to ClojureScipt map, but to access that field I will have to type monstrous unreadable access. Is there a way to do it nice and elegant way way?

(-> (aget (.-items response) 0)
    (.. -fields -image -fields -file -url))

or if you have converted it to a Clojure data structure:

(-> response :items first :fields :image :fields :file :url)

I recommend using cljs-oops library. It support nested "selectors" for your object graph, e.g.:

(oget o "k3.?k31.k311")
(oget o "k3" "?k31" :k311)
(oget o ["k3" "?k31" "k311"])
(oget o [["k3"] "?k31"] "k311")

I also use cljs-oops and do recommend it, but also wanted to show the vanilla cljs solution.
