Usage in the component is pretty much the same amount of code.
In both cases you need to wrap the app in a Provider (you forgot that in the context examples above)
creating a slice and creating the Provider wrapper pretty much abstract the same logic - but in a slice, you can use mutating logic, so as soon as you get to more complex data manipulation, the slice will be significantly shorter
That in the end leaves the configureStore call - and that are three lines. You will probably save more code by using createSlice vs manually writing a Provider.
But I had added the Provider in the Context example 😐
You are talking about using useReducer hook with the Context API. I am suggesting that if one is required to modify the data, one should definitely opt for Redux. In case only sharing the data with the Child Components is required, Context would be a better solution
Yeah, but you are not using the Parent anywhere, which is kinda equivalent to using the Provider in Redux, kinda making it look like one step less for Context ;)
As for the "not using useReducer" - seems like I read over that - in that case I 100% agree. :)
"I am suggesting that if one is required to modify the data, one should definitely opt for Redux." - can you elaborate? What specific advantages Redux has over using reducers with useReducer in React? Thanks!
@gottfried-dev The problem is not useReducer, which is great for component-local state, but Context, which has no means of subscribing to parts of an object, so as soon as you have any complicated value in your context (which you probably have if you need useReducer), any change to any sub-property will rerender every consumer, if it is interested in the change or not.

In the end, it usually ends up as quite some more code - see kentcdodds.com/blog/how-to-use-rea... for example.
But just taking your examples side by side:
