Learning the "vocabulary" ( partion-all, interpose, nthnext, nthrest, take-nth...)



def rabbits 
  [{:name "Fluffy" :color :white :size :large} 
   {:name "Chocolate" :color :brown :size :medium} 
   {:name "Hopkins" :color :black :size :medium}])

(def get-medium-bunny-names  ; defines a transformation on a process
  (comp
    (filter #(= (:size %) :medium)) ; note the arity of these two
    (map :name)))

(into [] get-medium-bunny-names rabbits) ; produces ["Chocolate" "Hopkins"]
