Why use react.useContext if you are already using redux? I am trying hard to understand what benefit react.useContext offers over redux. Is there something I am missing?
I am trying to deeper understand react.useContext and redux. So please explain why one is technically more suited for certain situation than the other. What are the technical differences?
Context and Redux do two different things.
Context is a mechanism to pass a single, seldom-changing variable down the tree. Whenever that variable is changed, all consumers rerender, so it is best used to pass down things like a Theme, or a WebSocket connection used in many components. It's more useful for dependency injection.
Redux on the other hand is made for managing plain objects (e.g. a WebSocket wouldn't go in here) holding data and subscribing efficiently to granular changes within that data.
So it is likely you will use Context and a state management library (there are also alternatives like MobX, Recoil, XState, Jotai, Zustand or Valtio) side-by-side, for different purposes. For more information, you can for example read this article.
