can Recoil stop update React Component update when atom value still same after update?

[xuzhanhh]

Hey guys! I want to stop rerender Component when atom/selector get the same value after updater. What should I do?

Here's the playground: https://codesandbox.io/s/stoic-resonance-vecxs?file=/src/App.js:758-811

actually, I try to normalize todoState in a atom(todoIdListState) and atomFamily(todoState) mapping in order to avoid updating all <TodoItem/>, but when I add a state filteredTodoIdListState whitch subscribe atomFamily(todoState), it will cause rerender <TodoList/> when I changing one todoState atom. How can I stop this rerender? Is there a way like react useState's internal compare check?

It looks like this commit might address that.

Setting atoms is addressed with #386, limiting re-renders of selectors with the same value is duplicate of #314
