Question

I am a Ruby newbie.
How can I write better for this function? can i use a hash table instead.

def readable_status(status)
  if status == "1" 
    return "go"
  end
  if status == "2"
    return "stop"
  end
  if status == "3"
    return "die"
  end
end

If you wanted to use a hash (as per your question) you could do:

def readable_status(status)
   readable = { "1" => "go", "2" => "stop", "3" => "die" }
   readable[status] || "default value"
end
