when everyone is trying to do the opposite (remove js from your html so that both are mean, see angularjs and similar), this one is extraordinary. I believe it has a fundamental flaw though. If someone is comfortable with this level of js, then she wouldn't bother probably having them inter-mixed. On the other hand for those who don't like a high doze js in their lives, this looks even scarier. So I think, it is not a niche but a deserting island market segment to aim for. Still, who am i to judge, all the luck to the maintainers
