I think this is the best solution if you're ok with regex.
Nice solution, mine was similar in using regex match, but not as short. This one will error on a string without any vowels because match will return a null which doesn't have a length.
That's a good point. This could be avoided by checking if the result of the match is null and using an empty string instead. Something like this:
I also used template literals before the match so numeric values or null would be process too... and now the code is even uglier than before :P
Good catch! I corrected it. Thank you for letting me know!
