Named parameters in Ruby 2

Question

I don\'t understand completely how named parameters in Ruby 2.0 work.

def test(var1, var2, var3)
  puts \"#{var1} #{var2} #{var3}\"
end

test(var3:\"var3-ne         


        

Answer 1

Firstly, the last example you posted is misleading. I totally disagree that the behavior is similar to the one before. The last example passes the argument hash in as the first optional parameter which is a different thing!

If you do not want to have a default value, you can just use nil.
