Interesting. Never thought of doing it that way before. Maybe a bad practice, but still a good puzzle.

Fixed

I highly agree, but it's not an issue. It's a suggestion, because it does not relate to the completion of the kata.

Are you somehow mutating the input array?

Tip: use the index of value(s) to solve this kata

This is a bad tip, and teaches people a bad practice. Please, remove it from the description.

Alright, I get it now.

if the number of the array's values is even return truthy values otherwise return falsy ones.

[ true, {} ] has 2 elements, and you have to return the truthy values in that array, so you should return the same array given true and {} are both truthy.

It says: when there are no corresponding values (false in this case) return empty array.

No, the corresponding values are truthy in that case.

Done.

It says: when there are no corresponding values (false in this case) return empty array.

if the number of the array's values is even return truthy values...
Number of values = 2
Truthy values: true, {}
Expected: [true, {}]

What's wrong with that?

[ true, {} ] gives '[ true, {} ]' as expected result. Shouldn't it be '[]'? I think the test cases are broken.
