tests not working at least in js

Thanks for the feedback. Please try again, it should work now.

Your tests are messed up, at least in coffeescript. Initial tests tell that identical arrays are not the same, random tests use 3D arrays for some reason.

Random tests are incorrect for some inputs in coffeescript! For exaple: Testing for nbMonths(2500 ,2500 ,1000 ,1.5) - It should work for random inputs too - Expected: [1,1000], instead got: [0,0]. It should expect [0,0]. Thanks!

Thanks a bundle - it works now!

Your tests in coffeescript give the following error - ReferenceError: pad is not defined. It looks like a problem on your end.

Things like that you should propose as friendly suggestions rather than marking them as issues. But thanks anyways, I've switched to assertEquals.

I'm glad you liked it.

The tests are passable, but provide poor feedback in terms of what's wrong if anything. It's not a very good kata the way it's written.

I think this kata is broken. Tests output has nothing to do with the solution code.

I think you're on the right track. Also, note that codewars' console interprets and prints certain things (like nulls etc) in a funny way, i.e. it doesn't print them. BTW, an empty array is not a sparse array.

I'm not sure you want me to tell you the answer - I think it spoils the fun of figuring out what the heck is going on. It is the whole point for katas like this. As a way of nudging in the right direction, remember than arrays in JS are objects.

I think the clue is in the description. Sorry if it looks cryptic.
