ClojureScript anagram implementation

anagram.cljs

; (group-by f list): call f on each item in list. The return value becomes a key 
; of the resulting map, whose keys map to the list of items for which f returned 
; that key.
; (vals map): returns a list of the values of the map.
(defn anagram [words] (vals (group-by sort words)))
