I'm struggling to define this specific type.
The goal is to create an open generic type ItemOrItemFactory<T> that encompasses either T or (..._: unknown[]) => T.
Something along the lines of:
type ItemOrItemFactory = <T> T | ((..._: unknown[]) => T)
However, this syntax is not valid. I find it challenging to understand how generics operate with the type keyword, and it's quite frustrating to search for solutions online.
It should appear as follows:
type ProductOrProductFactory<P> = P | ((..._: unknown[]) => P)
The {P} generic section needs to come directly after the ProductOrProductFactory<P> type declaration.
