Support for Maps and Sets

Does valtio support Maps and Sets?

Asking due to this discussion:

It's similar yeah. I would guess that Store deals with proxies better though, the library I wrote for that alone weights like double what Valtio weighs, and that's because it may support more built-ins (Maps, Sets etc.) and it ships which optimized comparators, rather than a general deep comparator, for almost every native methods those built-ins have, which improves performance dramatically when working with large objects where deep comparisons can get really expensive.

Valtio doesn't track mutations inside Maps and Sets. It would require lots of efforts.
Valtio's focus is in creating proxy snapshots which is important for concurrent mode and hook-based render optimization.

Got it. Wasn't aware that they behaved any different to objects or arrays when it comes to proxies.

Does valtio support Maps and Sets?

You can use MobX if you need to support Maps and Sets. I agree that Valtio should be kept simple.

We have Set support by emulation in https://github.com/pmndrs/valtio/releases/tag/v1.2.9

And we now have Map too!
