Rule proposal: `prefer-temporal`

See original GitHub issue

The Temporal proposal is currently stage 3. It massively improves date and time handling in JavaScript.

There’s a lot of potential for linting here.

We could block use of Date completely. Would probably have to be behind an option. But as far as I know, Temporal should cover everything Date currently handles.

Fail

Date.now()

Pass

Temporal.now.instant()

We could also potentially prevent use of popular date libraries like moment, Luzon, date-fns, etc.

More specific ideas for listing here wanted.

On second thought, why? Why would Temporal.Now.instant().epochMilliseconds be better than Date.now()? It’s just a number in both cases and there are no improvements (unlike the new Number.* methods).

I think such rule would make more sense for every Date method except Date.now()

Luckily we don’t have to decide this yet. We can make the option false at first and see how we feel about it after having used Temporal for a while.
