Hello,
As a challenge I need to convert a map structure to a csv structure.
So ( { :name "roelof", :city secret }) need to be converted to roelof,
secret.
I think I can use something like (map clojure.string/join ..) for it but
it seems I have to make a function out of the :name roelof par
ll) (reverse coll)))

I have now this :
(ns fourclojure.core
(:gen-class))
(defn checker [x]
( = x (if (string? x)
(clojure.string/reverse x)
(into (empty x) (reverse x)
(checker '(1 2 3 4 5)) true
( = '( 1 2 3 4 5) '( 5 4 3 2 1) ) false
So something is wrong about my code
it works fine wi
Thanks for the explanation.
For a beginner enough to learn

hello,
Suppose I have this test
(facts "do-a-thing" {:exercise 1 :points 1} (do-a-thing 3) => 46656.0 (
do-a-thing 1) => 4.0 (do-a-thing 0) => 1.0)
Is there a way I can only run this test
I tried lein midje :filter exercise 1
but that one fails.

Hello,
I found this MOOC to learn me clojure :
http://iloveponies.github.io/120-hour-epic-sax-marathon/basic-tools.html
Is this a good one or is there a better free alternative.
