Your suggestion is accepted and included in this kata.

var b = Math.floor(num - (a * 100));
console.log(b);
var c = Math.floor(num - (b * 10));
console.log(c);

Consider adding some console.log diagnostic commands to inspect variable vales. It should lead you to the right path.

Sorry but I don't understand what you mean. Lo should get it, since she is on guest list.
Age should be equal or above bouncers's age limit or *name should be on guest list to enter the club*.
Can you suggest message that would be easier to understand please?

I don't know how to assist with it.

Thx for your comment. I had a feeling that what you've mentioned is implicit feature request, but you're right kata is better with additional note. What do you think about adding: For empty array result should be 0.

Thx for constructive comments. Oh man, I guess I have to learn that. Is there a way for you to contribute kata edits? You sound like a perfect candidate IMHO.

Thx for your comment. I was hoping for this kind constructive discussion. However, because of [some excuse :)], I'm not willing to invest more time in rearchitecting this kata. I'm taking it down.

Thank you for your comment. Consider suggesting solution to upgrade it.

I've seen the translation. It looks good. Not sure if I've managed to approve it. Please let me know if I've succeeded?

Fixed. Thx.

Thx for the comment. Assumptions in kata descriptions have been updated.

Assume guest has valid age - number.

In attempt for this kata to focus on objects and methods, I'd like to ge away from handling null/undefined/NaN edge cases, that you'd handle in production code.
Can you accept is as a fix?

P.S.: I've checked your solution at: http://www.codewars.com/kata/reviews/565ca557179bdd532000006f/groups/584ef497ee7df471490005d1.

Approved.

Sorry I must've missed message from you. Is CoffeeScript translation still available?

Thx. Description is updated.

Can you point me to example of proving that code is actually debugged and not rewritten entirely, please?

Typo fixed. Thx.
