Value be Something OR SomethingElse

I'm trying to test that a value is one value or another. In either case it's considered passing but I have not been able to figure out how to test for this.

Does expect.js support this sort of assertion and if not how should I go about testing for it?

Start by reviewing the expect.js assertion API and documentation to determine whether an assertion can accept either of two values. Confirm the expected behavior from the issue, then clarify whether the outcome should be a supported assertion, documentation, or usage guidance.
