I'm also super interested about how code looks like in elite organization! In my previous work place I felt exactly the same as you.. Lucky for me there are many seniors with years of experience under their belts where I'm currently working.
This is an amazing read on the software controlling the space shuttle from 1996. Thanks for sharing!
For me elite just might be a company that meets my standards, which I realize is a useless description for anyone that's not me now. In fact, it's a lot of personal opinion - mainly code that's easy to modify and reason about I guess.
I realized I said "this bad" in my original post but, to be clear, I don't have any serious issues with the Twitch snippet - I meant "this" as software in general. The only nit I have is using `like any array(['%p1%', '%p2%'...])` seems like a more elegant and straightforward(?) way to write the logic.
