I didn't knew you could do that with a ternary operator, nice.

Doesn't have a place in production code, has to be more readable.

NICE!

I don't think using regex on a kata called "Regex validate [...]" is missing the point. This regex is also O(n) with respect to the input length, not O(1).

All of these solutions use REGEX. I mean.. it works, and is definitely the best practice because of O(1) complexity but it's also kind of missing the point imo.

You blew my mind with that solution 🤯

Would that not include 5? I thought it was inclusive if you did it that way.

Thank you for providing a WHY this is not best practice. Much appreciated.

Its usable for codewars only, IRL lead would beat ur ass for coding like that

( ͡° ͜ʖ ͡°)

Another level solution 👏

Oooh! I like this solution. It's quite clever. Nice work. 🙌

Thanks. Though I haven't updated this kata I feel I feel should mention that I created it before const and let were a part of JS. :)
