Why is the "command" being set to == y and not the "valid_command?"?

Thanks!

ruby.rb 
def valid_command?(command)
  if (command == "y") || (valid_command? == "yes") || (valid_command? == "Y") || (valid_command? == "YES") 
    return "true"
end
end

Hi Darian command is the parameter being passed into the valid_command? method, so all the logic operations, i.e. if statments, should be run on the command parameter. So if somewhere else in the code, the method was called like valid_command?("yes") then "yes" would get passed in via the command parameter and then you would compare that against "Y", "yes", etc. You would end up with the if statement looking like this:

  if (command == "y") || (command == "yes") || (command == "Y") || (command == "YES") 
    return true
  end
