expect(object).toBeSet() & expect(object).toBeSetOf(String)

[jrencz]

String is an example. It should be able to iterate over the Set and check if all its elements match the given type.

Thanks @jrencz, would you mind writing some example tests in here? What some key specs would look like using Jasmine-Matchers with this implemented.

[jrencz]

.toBeEmptySet would be useful as well

[jrencz]

@JamieMason do you have any way to handle host objects that are not present everywhere already defined in the project?

It's easy to write a polyfill but I need to include Symbol polyfill to implement Symbol.toStringTag properly.

[JamieMason]

I've not used Symbol before @jrencz, can you explain this some more?

[jrencz]

@JamieMason Symbol is a way to define most of those "magical" JS features present before ES2015. One of those is the host objects ability to define how Object#toString works when an object is passed to it. Set has Set[Symbol.toStringTag] similar to function () { return '[Object Set]'; }

For now I just opted out of testing in browsers without Set implemented, but I'd like you to hint me what to do if you already have a plan for such situations.

[jrencz]

and Symbol.iterator would be useful to be able to implement toBeSetOf. But then I'm going to need forOf loop anyway (in the most simple approach)

[JamieMason]

Thanks again for raising this @jrencz but I've decided not to add matchers for Set etc. A new project such as jasmine-set-matchers could be useful to people though if you decide to take it on.
