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

You can define named parameters like

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

If you don't pass one of the parameters, then Ruby will complain about an undefined local variable or method.
