I wouldn't expect there to be any.

Sometimes your presentation varies depending on the data, in ways that are ultimately Turing-complete. Any domain-specific-language is eventually going to grow to incorporate some kind of logic.

React seems to have found a sweet spot for that with JSX, which presents as if it's mostly HTML with some Javascript mixed in. (In reality, it's actually Javascript with HTML-esque syntactic sugar, but it works very hard to present the illusion.) That means that it's working in two well-understood and widely-supported languages, rather than creating yet another presentation language.

HTML+CSS has deep flaws as a presentation language, but it's also universal. I don't expect React to reinvent that particular wheel.
