Lexicographic string comparison

See original GitHub issue

🚀 Feature Proposal

JavaScript supports comparing strings: '2018-01-01' < '2019-01-01'. Jest should pass that through.

Motivation

I want to be able to easily compare ISO8601 dates.

Example

expect(date).toBeGreaterThan('2020-06-01')
expect(doc.updatedAt).toBeGreaterThan(doc.createdAt);

Pitch

Why does this feature belong in the Jest core platform?

I have submitted it to jest-extended already.

I think this would be better as a separate matcher to avoid confusion around why assertions with strings pass and to ensure users are explicit about what type they expect in the matcher. And because of its rare use cases, I would say it’s a better fit for jest-extended.
