How to repeat string n times in idiomatic clojure way?

Question

In Ruby, \"str\" * 3 will give you \"strstrstr\". In Clojure, the closest I can think of is (map (fn [n] \"str\") (range 3)) Is there a more idioma

Answer 1

Just to throw some more awesome and hopefully thought-provoking solutions.

user=> (clojure.string/join (repeat 3 "str"))
"strstrstr"

user=> (format "%1$s%1$s%1$s" "str")
"strstrstr"

user=> (reduce str (take 3 (cycle ["str"])))
"strstrstr"

user=> (reduce str (repeat 3 "str"))
"strstrstr"

user=> (reduce #(.concat %1 %2) (repeat 3 "str"))
"strstrstr"
