Make Collection.prototype.get fail gracefully when __paths.length === 0

[DrewML]

I spent more time debugging this one tonight than I'd like to admit :). Minimal Repro is here.

When calling .get on a collection without any paths, an exception is thrown. Unfortunately, because the exception message itself references get, I made the (poor) assumption that it was my call to get, not the implementation's call to path.get.

Would you be willing to accept a PR to change the behavior here? I think either returning a falsy value (maybe null, similar to document.querySelector) or throwing a more specific error (encouraging the user to check Collection.prototype.size first) would work.

I would certainly accept a pull request to improve this 😃 .

Which behavior would you prefer? I feel like throwing an error might be more helpful?

Yeah, I think you're right. Returning something would probably still lead to less-than-helpful failures anyway, since code will likely chain off of get.

I'll submit a PR for that change.
