I understand the spirit of your comment, but this was/is also true of Google Web Toolkit (GWT).

I’m going to have to take that on faith, their site doesn’t appear to ship the JS necessary to open the nav menu. But clicking through a few links confirmed what I recall: the major difference (apart from language) is the component/templating approach. Not that one is inherently better than the other (though I do personally prefer JSX), but bringing this concept to a dev environment which thus far mostly lacks it is a good thing for users. And with more flexibility in variety, there’s better odds users will get that experience.
