OP solved it, closing

Your solution has, unfortunately, more than one problem, but you are also interpreting the result of your printing incorrectly.

In your solution function, you have: return text;. But your printing is:

console.log(`${sentence} ${nums.join(' ')}`);

So effectively you are not printing your result (which is returned by your solution), but something else.

And again, you did not manage to get it working. It appears to be working because your method of verification is faulty. If you'd manage to get it working, it would successfully pass tests :)

Read this article and see if it helps: https://docs.codewars.com/training/training-example

You can also ask for help in #help-solve channel of Codewars Discord.

What do you mean by "working"? If it were working, it would pass tests, wouldn't it?
