I think it's bad practice to modify a parameter within a function unless that's the purpose of the function.

Didn't know this. Thanks!

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

yes, it is just the condition of kata says you don't need that

Well, but you can add a validation for arguments to check if they're positive

If dragons == 0 then it will be mistake

You're a genius!

I wrote the same way

Ah, that makes sense. I'll have to declare those in the future. Thank you for explaining :)
