Yeah, I know what you mean. And I agree that something like that could be faster than react if it were written in C++. But if we're going to bake something into the browser, I'd like it to be something good. The "Regenerate big chunks of HTML then do expensive tree-diffing operations" approach is, as you say, always going to be less efficient than how Svelte or Solid render. I'd much rather skip DOM diffing entirely and go straight to that.

Nice - thanks for the example. I suppose the trick is implementing this in such a way that it doesn't depend on "watching" a variable in javascript. (Well, or we'd need to also add that as a feature to javascript - which would be a bit wild.)
