Question

I can generate a few lines of code that will do this but I’m wondering if there’s a nice clean Rubyesque way of doing this. In case I haven’t been clear, what I’m looking for is an array method that will return true if given (say) [3,3,3,3,3] or ["rabbits","rabbits","rabbits"] but will return false with [1,2,3,4,5] or ["rabbits","rabbits","hares"].

Thanks

Answer 1

class Array
  def same_values?
    self.uniq.length == 1
  end
end


[1, 1, 1, 1].same_values?
[1, 2, 3, 4].same_values?

What about this one? It returns false for an empty array though, you can change it to <= 1 and it will return true in that case. Depending on what you need.
