Just a heads up, another missing extern inference case: https://clojure.atlassian.net/browse/CLJS-3377 

(defonce ^js elk (new elkjs (clj->js {:algorithms algorithms})))
^js should not be necessary here

@timothypratley thanks for the report

indeed new case in the analyzer does not preserve the tag on the constructor

Hey @U050B88UR I don't know exactly the implications of map js/Boolean to boolean, but new Boolean(false) actually returns an Object, that always evaluate to true. This wired case occurs in JVM: you can create a Boolean object and in a if it will always evaluate to true

@U2J4FRT2T that isn't relative to type inference though, that's just a runtime host behavior thing
