Considering the differences lean towards the DOM interface names for given attributes and properties, I wouldn't exactly call it NOT JS.

It's actually an XML abstraction that closely resembles HTML + JS-DOM, and is then converted into function calls and arguments.

It's also about as close to E4X as an abstraction that I've seen and something I wish was cross browser over a decade ago when it was first introduced by Mozilla and Adobe, but that's a long side-track. In the end, it's very effective and works well imho. Yes there are some more complexity points in some places, but I don't think anything else does it better. Vue imho is comparible, but I don't like it as much and I feel that Angular is far worse in practice.
