Sorry, I am sure you could use JSX with DIO.js too. To be honest, I wasn't even looking at the JSX. I grabbed it from where I found it. The takeaway is not JSX, but the fact that they use classes and that's all.

Personally, if I was going to go with this kind of architecture, I'd choose Preact (or React if I can't help it) to tap into the massive React ecosystem.
