Actually, this won't work with union types! The definition of `Equal` I use is this one: type Equal<X, Y> = (<T>() => T extends X ? 1 : 2) extends <
T
>() => T extends Y ? 1 : 2
? true
: false; Understanding this requires a bit more context, but I'll explain why we need something so complicated in the Advanced Union Types chapter :) I picked it from https://github.com/type-challenges/type-challenges which is an awesome resource too |
