Object.observe() is an upcoming feature for JavaScript, which allows you to add listeners to object's properties changing. With that, you could do the same thing as this library, but without this library. Still, I'm a fan of reactive programming, so thanks for this anyway!

I wish this were true, but unfortunately not. Object.observe doesn't provide any 'read' notifications, so you wouldn't be able to detect dependencies like this does.
