So in a language with nullable types, are you against a boolean ever being nullable? Null means “empty, missing info”. Let’s say we have role variable with a enum type of possible roles. It could still reasonably be nullable, because in some scenarios you don’t know the role yet, like before log in.
In any use case where we need to store some boolean, it’s a common occurrence that we don’t have the data and it’s null. It would be overkill to use an enum with True, False, NoData for these cases, where there is already a language feature made just for that, nullable values.
I’ve never used TypeScript, just writing from experience in other languages.
Yeah, but if it is about being an admin or not, hence the bool, it’d be idiomatic and reasonable to assume it to be false if we have no data. Unless we want to try and allow admin access based on no data. Having three states for a simple binary state is weird. And if it is not about just being an admin or not, the bool is inherently a too limited choice for representation.
