What does this "#" mean in this Clojure context?

Question

I came across an official Om example in the "examples / mixins" section, there is a definition:

(def MyComponent (let [obj (om/specify-state-methods! (clj->js om/pure-methods))]
    (aset obj "mixins" #js [TestMixin])
    (js/React.createClass obj)))

What does "#js" mean? I could not find the Clojure documentation for the "#" symbol when it was used this way.

Answer 1

From the Om tutorial :

#js {...}and #js [...]- this is what is called a reader literal. ClojureScript supports data literals for JavaScript through #js. #js {...}for JavaScript objects:

#js {:foo "bar"}  ;; is equivalent to
#js {"foo" "bar"}

Answer 2

Om Clojurescript. Clojure Clojurescript, .

#js , edn, , , #js Javascript. .

Answer 3
