Maps with multiple collections

As long as the function used can receive the number of params you're passing on, you can pass multiple collections to map.

(map str ["Y" "Y" "Z"] ["y" "y" "z"]) ; => ("Yy" "Yy" "Zz")

You can pass the map a collection of functions.

Functions have always the same structure: an operator and n operands. The operator can be a function or an expression that returns a function.

(+ 1 2 3 4) ;; => 10
(* 1 2 3 4) ;; => 24
(first [1 2 3 4]) ;; => 1
(or + -) ;; => returns another function: + (PLUS) in this case
((or + -) 10 20) ;; => 30
((first [+ -]) 10 20) ;; => 30

Clojure structure is always the same

(operator operand1 operand2 ... operandn)
(str "you say goodbye" "...and I say hello!")
(+ 1 2)
(map inc [1 2 3 4])

if statement
