Discussion on: Daily Challenge #3 - Vowel Counter

[Ryan Smith]

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:

f=s=>(`${s}`.match(/[aeiou]/gi)||'').length;

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

Typo ${s}

f=s=>(`${s}`.match(/[aeiou]/gi)||'').length;

[Alvaro Montoro]

Good catch! I corrected it. Thank you for letting me know!
