I can relate to this idea, but I gave a try to react and I changed my position:

Here's why IMO react is not actually mixing the two: HTML is just the serialized form of the DOM, your browser reads it, transforms it the a DOM tree before rendering it.

With react, you interact with the DOM (indirectly via a virtual DOM API), so you manipulate javascript objects, you only do javascript. JSX is just syntaxic sugar over that API, because deep nesting is easier to read with XMLish syntax. JSX is not a templating language (that outputs a string).
