A wild Python appeared!

Noted, nice kata btw.

Confirmed.

Hint: no overly large array of strings is needed to solve this kata.

While it could technically contain any number of elements, that is not what the description specify.

Sheldon, Leonard, Penny, Rajesh and Howard are in the queue for a "Double Cola" drink vending machine; there are no other people in the queue.

A java kumite for your javascript

Lua translation kumited.

Translation includes random tests and all numbers less than 1 edge case test.

Tests do not cover all non-positive numbered edge case.

ie: -1, -2, -2

Tested on Java and Ruby.

Python (and javascript) solution does not require throwing errors from the solution method, and thus does not test one's ability to check for and raise errors.

Is this intended?

Ruby solution boilerplate does not have method arguments.

Normally I would agree. But there is a limited number of testable outputs here due to factorial's tendency to overflow from exponential growth.

For example, you cannot go above 18! without exceeding javascript's and typescript's MAX_SAFE_INTEGER, nor can you go above 20! without overflowing csharp's ulong.

Your welcome!

Very.

May I still add additional languages after this goes live?

Thanks!

I don't mind, I allow contributors for a reason. ^-^

I invalidated your solution btw. ;)

Anything else you spot?

Changes migrated to coffeescript kata.

Javascript kata now test floats with an epsilon of 0.01.

I've hopefully solved both issues on the javascript kata.
