Hi José,
user=> (apply str (repeat 3 "code"))
"codecodecode"
will give you what you want,
if we break it down,
user=> (repeat 3 "code")
("code" "code" "code")
repeat will give you a sequence of xs,
since you don't know the length of the
sequence at compile time we apply str
to the sequence
(apply str '("code" "code" "code"))
which basically expands to,
(str "code" "code" "code")
then you get,
"codecodecode"
