Got any handy assertion functions for comparing JSON documents?

Not yet, but there have been similar questions already, I'll open an issue for it

for the use case I'm working on at the moment, I do want to assert that the two documents are equivalent, so unexpected data should be a fail.

I see, and you are looking for something like:

assert(json).isJson(doc)

right?

yeah

ok, two different use cases, I'll write that down. Thanks for your input 🙂

Array order is important! Object property order doesn't matter to me here, which I think is going to be the common case.
