Thanks for completing the Kata, a good and compact solution! I just used plain text spaces in the test expectation as Codewars displays in plain text.

Yes, only the name in fruitsName is fruit ;-)

The list is preloaded for you under fruitsName in JS and $fruits_name in Ruby.

I tried a few solutions in JS: no problem. See if you don't have an extra "\n" at the end of your result.

Please which language?

the Test failure message puts a comma between expected and instead got, it's a little misleading that way. You might have some trailing whitespace if it's failing only on the random tests. Hope that helps
