Depends on what your definition of "magic" is. For example, we specifically have a "Reducing Boilerplate" docs page [0] that talks about writing reusable logic for reducers and action creators, like "higher order reducers" or a `createReducer()` util that accepts a lookup table of action types to handler functions. There's many existing libs that implement this kind of pattern [1]. Beyond that, there's other libraries that provide a higher level of abstraction, like automatically generating logic to handle common use cases (normalizing data, updating certain fields, etc) [2]. Updating data immutably can become complex [3], so there's a lot of immutable update utility libraries out there [4]. I recommend Immer [5], which lets you write normal mutative code but then applies the updates immutably. Finally, there's frameworks built on top o
