Immer

Immer is a JavaScript library that enables immutable state management by allowing developers to write mutable code while producing immutable updates. It uses a concept of a 'draft state' that can be modified directly, but produces a new immutable state behind the scenes, making it easier to handle immutable data structures in a more straightforward way.
