Another point I'd like to make is that you don't really need reactivity. Frameworks like Mithril or Imba are not reactive, at all, and they work just fine for many use cases. The advantage is that state can be just vanilla JS. No need for any abstraction. For example Mithril re-renders everything to the VDOM after a user event (click, etc) automatically. You can also tell Mithril to redraw [0] eg if you have a WS handler or something state change not related to user input. I think Imba works very similarly but I don't have much experience with it. It's a super simple mental model which I like a lot more than anything else. I'm mainly using Svelte now though for other reasons.
