It depends on your tsconfig. An empty array could be typed as never[], forcing you to annotate it.

I don't believe this is correct. There's no settings that correspond to that AFAIK, and it'd actually be quite bad, because you could access the empty array and then get a `never` object, which you're not supposed to be able to do.

`unknown[]` might be more appropriate as a default, but TypeScript does you one better: with OP's settings, although it's typed as `any[]`, it'll error out if you don't do anything to give it more information because of `noImplicitAny`.

Which setting specifically? Can you repro in the typescript playground?
