Hello,
For a exercise I have to add something to the end of a existing map.
So I thought this would work :
(defn add-author [book new-author]
(assoc book (conj :authors new-author)))
and call the function with :
(add-author little-schemer {:name "Gerald J. Sussman"})
then I see this error message :
ClassCastException clojure.lang.Keyword cannot be cast to
clojure.lang.IPersistentCollection clojure.core/conj (core.clj:83)
