“What’s a union?”
“Okay… then what’s a discriminated union?”
“Okay… let’s apply destructuring to one…”
“Okay… now what would analysis look like there given what I know?”
“Okay… how do we have the computer know what I know intuitively as a human given this context?”
“Okay! I think I got it!”
:-). If you’ve gotten this far with programming to understand the examples above, my guess is if you just take the time you can do it without the examples if you take it in small enough chunks :-).
Life’s all about what you apply your energy too
(And also, wonderful example :-) )

I can walk through it with enough pause, but it kinda makes my head implode when I glance at it.

TIL that you can disable ? and readonly in mapped types using -. So in the above code, every Key will be mandatory (-?) even if the original one in KeysType was optional.source: https://www.typescriptlang.org/docs/handbook/2/mapped-types....
I guess in a way, the issue is that it is cloaked with familiarity. Your brain gets so used to understanding sentences on first go it’s not used to not understanding it.
However, if it was a chemistry equation and you weren’t familiar with chemistry it would immediately understand that comprehension would take time and thus the mind implosion due to a lack of understanding doesn’t occur.
