Proposal: ReadonlyDate

[sindresorhus]

Type description + examples

Would be annoying as input, but can be useful as a return value.

type ReadonlyDate = Omit<Date, `set${string}`>;

I think that kills it, because you can't assign this return value to anything that accepts Date, so it's barely "read-only". Having to use date as Date every time isn't great

Would probably be better to do this as a typed readonly wrapper / proxy to Date with a way to get a full date.

const foo: ReadonlyDate = new ReadonlyDate();
const bar: Date = foo.getDate();
