Hi all
a = [:one, :two, :three, :six]
b = [:two, :four, 
six]
I want to extract the values of two arrays which exist in both ones (a
and b):
# => [:two, :six]
Does there exist a method for this?
Thanks
Josh

How about the elements that are in one but not the other array?
Where are these methods documented?
Thank you

Thanks! But right - where are they documented?

You're looking for "a - b", in that case.
http://ruby-doc.org/core/classes/Array.html
Hope that helps.
