regex is amazing.

you told already what i was thinking to say. well done. 👏

as the name of the function says reverseSeq, i prefer to reverse the array.

Another level solution 👏

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. :)

your code is clear and readable, but one thing, avoid using Var.

Thank you.
