I strongly agree with the premise of the article - HTML could be a fabulous substrate for computational notebooks!

But I didn't love the choices for how to implement it here. Dynamic, reactive HTML can be a lot more declarative than this, and Observable is cool, but strays from standard JS.

I started to build a reactive HTML system called Heximal that eventually will have notebook support, but it's declarative, based on HTML templates and custom elements with a expression / reactivity system (based on the TC39 Signals proposal) on top.

https://github.com/elematic/heximal

It's a bit like a mashup of HTMX, Tangle, Curvenote, and Polymer. Or like HTML if were natively reactive.

I think it will lend it self to graphical editing and notebook user cases quite well.

Are you taking into account Observable Framework here? That came out in March and one of the major features was that it uses standard JavaScript, not the syntax hacks they invented for Observable Notebooks: https://observablehq.com/blog/observable-2-0#a-better-develo...
