How to trigger focus and scroll across the app?

maybe a handleClick or similar triggers a store.setState('randomInt', Math.random()...)

Does store setState check for equality before updating signals?

Interesting, so map() is tracking everything, good to know!

Does store setState check for equality before updating signals?

What I meant is that the SO post shows the dangers of using proxies directly. Now AFAIK Solid doesn't allow anyone to do this, we can only modify it with setState. So none of the dangers in the SO post apply to us (or I didn't quite understand the SO post) I started watching the flux video, haven't finished it yet.

I've read the SO question, but I think Solid is protected from this, isn't it? Basically setState makes sure you are treating everything like an immutables, isn't it?

Does store setState check for equality before updating signals?

Right now, I feel happy to use stores for like 99% of things, except state which is very much scoped to a UI component.

OK, I read the untrack docs, it's something different. I never used untrack before.

Does store setState check for equality before updating signals?

OK, I understand this part, it's like how we always have to write the full props.... versions with long variable names, we cannot just use local variables in Solid components.

Does store setState check for equality before updating signals?

I'm reading the TodoMVC app, but first I'm trying to understand what's happening here: https://playground.solidjs.com/anonymous/cbaca548-0499-44b5-851b-f98ff0abc470 The DOM is updated, the "direct" console line is printed, only the "on" version is not.

Does store setState check for equality before updating signals?

I mean for performance reasons, I want to avoid unecessary signal updates as much as I can. So I'm thinking of using reconcile everywhere. But then createEffects won't work.

Does store setState check for equality before updating signals?

It seems to be a limitation of createEffect, not setStore / reconcile

Does store setState check for equality before updating signals?

I think it does trigger, it just doesn't trigger the createEffect: https://playground.solidjs.com/anonymous/0ed192e0-1eba-4969-88c5-8abe61896944

Does store setState check for equality before updating signals?

Now this one definitely puzzles me (// This doesn't trigger store.selected because the array is preserved)

Does store setState check for equality before updating signals?

I understand. I just don't see why would I ever not use reconcile? I mean I can even imagine the idea to simply put it inside setState and always call it.

I see, great to know! Thank you for the snippet. So as a general rule, I don't need to use reconcile for simple types but need reconcile for complex types.
