it is not.. in javascript, anything divided by zero equals to infinity..

so infinity will always be greater than 2

Unless of course, it is negative infinity haha..

in that case negative infinity will always be lesser than 2

And also, if you got 0 dragons to kill and 0 bullets to use

in javascript, 0 divided by 0 will be NaN

Well.. the story clearly says there will be dragons and as a hero you should always bring a weapon if you're gonna kill that dragon..
so negative bullets is highly unlikely
also, 0 dragons and 0 bullets

But you got a point! HEHE

If dragons == 0 then it will be mistake

You should make pretty your code. The solution is ok, but is hard to read if you dont make it pretty.
