I'd add this:

Note: for this kata y isn't considered a vowel.

Do you need the vowels listed as a, e, i, o and u?

Your task is to write a function that takes a string and return a new string with all vowels removed

It's kinda all there.

+bool converts true => 1 and false => 0
0-index gives first element of array => 'No'
1-index gives second element of array => 'Yes'
