Before authoring a kata, solve more katas, use the search function to check if your idea wasn't already used in another, check how random tests are made (they're almost mandatory nowadays).

Duplicate kata; the task of filtering characters from a string has been covered.

Duplicate of this, changing odd for even is not enough.

The describe text is still: 'twoOldestAges' change that when creating a kata.

Hi,

Well, this kind of task already has been done again and again. ;) I advise you to unpublish it quickly (before it gets retired).

In any case:

• would need random tests
• missing edge case: empty array / only odds / only evens

And you should read those articles before trying to author another kata:
