At some point, the creator of SolidJS, Ryan Carniato did a stint helping developing Marko.js, a fine-grained reactive / compiled / a bit HTMX-like system, and blogged about that. It's a framework that originated from eBay. I'm now quite interested about the next version of Marko.js, Marko.js 6, and I'm gonna try it for my new project.

I'm interested in fine-graned reactivity so Svelte and SolidJS have been on my radar, but the HTMX-style approach appeals to me.

Here's something to munch on:
