One thing that always made me a little sad about transducers was how map lost its ability to iterate multiple collections in parallel. This is actually my favorite feature of map. For example:
(map + (range 5) (range 5 10))
=> (5 7 9 11 13)One somewhat practical use of this is if you want to compare two sequences, pairwise, using a comparator. Though I wish that every? took multiple collections, this is an adequate substitute:
| (fn [input] | |
| (if (coll? input) | |
| (= input (reverse input)) | |
| (= input (clojure.string/join "" (reverse input))))) |
| (fn [num] | |
| (take num (map first (iterate (fn [[a b]] [b (+' a b)]) [1 1])))) | |
| (partial reduce +) |
| (fn [coll] | |
| (reduce conj '() coll)) |
| ;; Count a sequence | |
| (fn [coll] | |
| (reduce (fn [c _] (inc c)) 0 coll)) |
