Clojure Values in Clojurescript -

I am testing Ohm () and I did not understand what happens here:

I have a closing code that uses an API and puts data into a vector. Then in my cloverscript script I try:

  (DRF URL (map (FN [C] (C: URL)) BILLINGS (DEAF ANN (FIRST URL)) (printline N) ;; Correct value (.log js / console n);; can anyone explain this behavior?  
 thanks   
 
 
 If you are using REPL, then  println  assumes that you have not released  (enable-console-print!)  - Usually print in your RPL However,  console.log  goes to your browser's console output. 
 
 When you call  (.log js / console n), then REPL prints Return value of  console.log , so that you can see  zero .
