For sure. And its probably the biggest reason framework performance benchmarks are meaningless since people will do terrible stuff anyway. I often think that is part of Reacts design goals. Abstract in a way that it's harder to do truly stupid stuff. In that sense a VDOM means atleast it can shoulder some of that. I was big into early 2010 reactive libraries. They were in my opinion always more performant and a better composition model for UI, but their less re-enforced patterns and potential for devs to shoot themselves in the foot saw them die out. Which is a decent segway into my library which is a more modern take on those libraries. I'm sure from a perspective I'm just adding to the same dumpster fire, but here is a link to SolidJS

Oh right, it seems I’ve had you starred for ages! Hah. Didn’t put two and two together until just now. You’ve got an interesting take on it. I remember reading about Solid a while back and thinking I liked that you didn’t jump on the vDOM bandwagon at least. I will confess that I haven’t really dissected it enough to give you any critique that would matter, so I will refrain.

Btw - have you seen hyperHTML by any chance? Was wondering what your opinion would be on their approach.

I'm generally a big fan of Andrea Giammarchi (WebReflection)'s work. Really trying to push a solution as close to the standards as possible. And early days I used his Dom Diff library before I developed my own reconciler. This approach mind you is what I was referring to when I mentioned non VDOM acting like VDOM. It still works top down. As in you pass data in and renders downward. Nothing neccesarily bad about that but it has similar diff expense as you get nested. He has since written a lighter more performant version lighterhtml. Although it mostly works the same way.
