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;
