My confusion is that nil is false and will return true if nil false on all other truthy values. It's a double negative same as clojure-noob.core> (false? false) true This is the better link https://clojuredocs.org/clojure.core/nil_q user=> (nil? nil)trueuser=> (nil? 0)falseuser=> (nil? false)falseuser=> (nil?
