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

I'm also not sure what your regex is trying to achieve, so I can't suggest a fix. But for the entire method, I'd keep it simple by using the === operator and making the regex case-insensitive with the i option:

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

Answer 2

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.

Answer 3

This works too

    def starts_with_consonant? s
      return /^[^aeiou]/i === s
    end

Answer 4

try this...

def starts_with_consonant? s
  /^[^aeiou\d\W]/i =~ s ? true : false
end
