React Context vs Redux

Coupling useContext and useReducer looks a lot like Redux. They both have:

• store
• reducers
• dispatching of actions
• a way to pass down that value and read it in nested components

The main issue with Context is that all subscribed components will re-render. This is not an issue most of the time.

My personal summary is that new context is ready to be used for low frequency unlikely updates (like locale/theme). It's also good to use it in the same way as old context was used. I.e. for static values and then propagate updates through subscriptions. It's not ready to be used as a replacement for all Flux-like state propagation.
