Question about full_name method

Hey, so I'm having a hard time fully understanding why in the full_name method we have the "@" in front of middle_name.nil? I tried both with and without the "@" and my code still works the same. Could someone better explain why we use this?

Thanks in advance.

KRIS NIKOLAISEN thank you for the link, but I was wondering too, and couldn't find an answer in the link, why does Jason only use it in the if statement?
