console.log("Hello") is not more complicated than print("Hello").
For the callbacks it is actually possible to not use them. See how to: http://www.xul.fr/javascript/no-callback.php (and it is even very simple). That is just a matter of style.
Actually, it is (it requires a package prefix) and it's:
print "hello"
Yes, you can use promises instead of callbacks, and get in promise-hell instead of callback-hell. It's indeed a matter of style.
