If statement in Ruby using Regex

Question

Everything seems to be working fine except the commented line:

#return false if not s[0].upcase =~ /AZ/

and the fourth check.

What is t

Answer 1

It's easy with regex:

def starts_with_consonant?(s)
   !!(s =~  /^[bcdfghjklmnpqrstvwxyz]/i)
end

This matches the first character of the string with the set of consonants. The !! forces the output to true/false.
