Cell updates

It's easy to update cells depending on their previous value:

const counter = proxy.new(0);
// ...
counter.update((prev) => prev + 1);

Note that update functions should return new arrays and objects, for instance using spread operators [...prev, new] and {...prev, field: new}.

If you need more complex imperative updates, we suggest you to use immer:

import { produce } from "immer";

const patch = (prev) => {
  // complex updates...
};
cell.update((prev) => produce(prev, patch));
