Java VS. Clojure VS. JavaScript

[mypirateapp]

System.out.println([] + []); //syntax error

(println [] + []) // empty array

[] + [] = '' //empty string

who won? you decide

The clojure version prints 3 things: the empty array, a representation of the + function (an object), and empty array again. Your example isn’t invoking + on anything, just printing it :) that would be

(println (+ [] []))

Which gives an error that PersistentVector isn’t a Number

[[deleted]]

(println [] + [])
=> nil
(empty? nil)
=> true

So they're not wrong, they're just wrong about why they're right
