best one for me

Sigh, I need to paractice a lot to get this level :|

This is so clever and looks so simple. Kudos

Great solution, didn't see this until I cleared and after reading it seems obvious. Good job.

I don't understand why this works. I first tried to do it my own way and I got a few errors. Then I tried this code and it says it's good, but if I test it for use cases my code failed, you still get the wrong answer but still pass the problem somehow.

My code failed for those 2, but your code wors fine even if still fails. Why?
console.log(createPhoneNumber(['(', 1, 2, 3, 4, ')', ' ', 5, 6, 7, '-', 8, 9, 0])); // ((12) 34)- 567
console.log(createPhoneNumber(['(', 1, 2, 3, 4, ')', ' ', 5, 6, 7, 8, 9, '-', 0])); // ((12) 34)- 567

From all the solutions, this is definately the most elegant one. Thanks man, seeing this I just learned how to work with formats in shape of variables.

You are Amazing

Me, looking at my long ass solution and then seeing this:
