I'm going through the Do Things: A Clojure Crash Course, and the following
example (in REPL) is presented:
(defn recursive-printer
([]
(recursive-printer 0))
([iteration]
(println iteration)
(if (> iteration 3)
(println "Goodbye!")
(recursive-printer (inc iteration)))))(recursive-printer); => Iteration
0; => Iteration 1; => Iteration 2; => Iteration 3; => Iteration 4; => Goodbye!
This works as expected, but I don't understand the syntax of the function
definition. Specifically: (defn recursive-printer ([] (recursive-printer
0)). Isn't the parameter list supposed to be a vector [] not ([]...)? Also,
I don't see how [iteration] is resolved on the next line.
Thanx for any help!
