How do I print a list of numbers on each line in clojure?

Question

how can I print a list of n, say 10, numbers on 10 lines? I just learned about loop and recur, but cannot seem to combine a side-effect (println i) with (recur (+ i 1)) in a loop form. Just to be very clear: I'd like output like this:

1
2
3
4
5
6
7
8
9
10

when n is 10.

Answer 1

I suggest dotimes for this kind of simple loop:

(dotimes [i 10]
  (println (inc i)))

Note that dotimes is non-lazy, so it is good for things like println that cause side effects.

Answer 2

You can use doseq for this, which is meant to be used when iteration involves side effects,

(doseq [i (range 10)]
   (println i))

You could use map as pointed but that will produce a sequence full of nils which is both not idiomatic and wastes resources also doseq is not lazy so no need to force it with doall.
