hey couple of things I see in code some times when i search for with google i get other similar things come up so thought i wud just ask here

first is refencing a object with a ? aka obj?.name - I’m guessing its some kind of check to see if it exists or something

second is ?? I know what ? is used for and whenever I try and search for ?? I just get information about ? which is kind of annoying lol I’m guessing its similar to && but I just don’t know what its about pls help!
