Clojurians Log v2

Is this the idiomatic way to initalize a JS object? I tried but was unable to wrangle it into a doto form.

(let [img (js/Image.)]
  (set! (.-src img) "foo.png")
  img)

(doto (js/Image.) (set! -src "foo.png"))

I saw this link with cljs.reader https://cljs.github.io/api/cljs.reader/read-string

when I use it, I get undefined

Do I have to import something and/or add a dependency?

@ps (:require [cljs.reader :as reader]) in ns and (reader/read-string ...) after

thanks @thheller
