I also believe that it is redundant. But only if you use
--noImplicitAny. We all know that using
any is a criminal offence in TypeScript, right? (Attempted joke)
So since TypeScript doesn’t allow implicit
anys, everything is sensibly typed (unless you specify
any explicitly, so add es-lint
no-explicit-any to avoid prison time), TypeScript will make sure that all the function returns are properly typed and used accordingly.
And this way we gain more flexibility when having to change function signatures. Imaging changing
id: number to
id: string in all the project? So for more flexibilty you can also use
id: Entity["id"] – longer to write but never breaks.
