I'd love to see more tutorial series' where you create apps to completion. I find those to be the most helpful videos on your channel. Thanks for all you do!

[@arunvasantharajan440]

please Add closures and generics and other complex topics as well, you are a great Teacher, Thank you Nick

[@SwiftfulThinking]

Closures are in the Continued Learning playlist.
These courses are in order, so you won’t need to use closures until then!

Can you use intersections to compare more than 2 things, such as console exclusives from PlayStation, Xbox and Nintendo Switch

[@KevinCodeingology]

I have a particular question: let's say you are trying to make a sort of gacha game, so you need various 3d models, and you also need the rarity (like common, rare, legendary ecc, which would be the droprate of those models when you try to get them)
in this case, would arrays be the best choice to insert all the 3d models in? even tho there are like over 100 of them?
And what about the rarities? Should you make a struct with the rarities variables or an enum is a better choice? or perhaps another array yet again?
