Error in the instructions:

objectToArray({2:5, 9:1}) => [2, 2, 2, 2, 2, 99]

It should read:

objectToArray({2:5, 9:1}) => [2, 2, 2, 2, 2, 9]

An error in the test cases prevents a valid solution:

var obj = {none:0, nada:0, rien: 0};
Test.assertSimilar(objectToArray(arr),[]);

It should read:

var obj = {none:0, nada:0, rien: 0};
Test.assertSimilar(objectToArray(obj),[]);

Accepted, thank you

Marking this resolved, since I don't see the need for another test case.

Would you explain what "some submitted solutions fail" means, and how that failure is caused by an uppercase vowel in the string? I'll be happy to add another test case if it's warranted, but I still don't understand your original comment.

I don't understand — would you explain in more detail?

Great. I attempted to do the same yesterday evening but for some reason was unable to re-publish.

I'm marking this resolved. Would it be worthwhile for me to incorporate numerals and underscores etc. into the remaining random tests, or would that be overkill?

Great, thanks. Both are approved now.

Thanks! I see that the Haskell translation includes an additional test (of string helLo wtuorli) to make sure all five vowels are covered; but I don't see the same test added in the CoffeeScript translation. (Clever solution on the latter!)

Attempted to approve both translations, got error Description cannot be approved, recent changes from related record must be merged first.

At @Insti's suggestion, I added one additional test to my previous version, to make sure all five vowels are covered. (That test string is XaeiouX.) You could also add that if you want.

Now using s instead of str in Python. Also added random tests for JavaScript, Python, and Ruby. Thanks!

Added random tests for JavaScript, Python, and Ruby. Thanks!

Added static test including all five vowels for JavaScript, Python, and Ruby. Also added random tests for JavaScript, Python, and Ruby. Thanks!

Now using s instead.
