( JS, possibly others )

JS by convention uses camelCase. The initial solution and the tests use different other conventions for naming the solution.

That's just bad, bad, bad .. :/

( Please don't fix this. Please just unpublish. Because of the other issue. )

Aliasing built-ins is a worthless kata idea.

Moreover, the kata makes no sense:

• any non-zero number can divide any number
• the largest number dividing some arbitrary x will always be Infinity
