In true Ruby style, we could monkey patch the Array class, like such:

class Array
  def are_anagrams?
    self.map { |w| sort_alphabetically(w) }.uniq.size == 1
  end
end

So then we could call:

["pots", "post", "stop"].are_anagrams? # true
["pots", "post", "ghost"].are_anagrams? # false

Looking up methods on the Array class, I see that I can refactor the above to:

def are_anagrams?
    self.map { |w| sort_alphabetically(w) }.uniq.one?
end

This may be less clear to non-Rubyists, but that method is there for a reason for Ruby folks.

Very cool
i'm learning ruby currently and the refactor steps are very clear and easy to follow.
At then end only one line method!
i would have written this in 20 lines probably and in a couple of hours :)

Cool stuff.
