Hi, there are some issues that I have noticed with your kata so far:

• there are no random tests
• there are no sample tests
• the initial solution has an incorrect function name, causing errors to be raised
• for the first two tests, the original array contains integers, whereas the expected output contains strings
• for the last two tests, the original array contains strings but tests are missing quotation marks

If you haven't already, I suggest reading this

cheers :)
