Should state be completely migrated to Redux, and if not, when should you use local?

Question

React

When do you need to use store redux-a, and when do you need to use react's local state? Passing one of the paid courses, I saw how the author partially uses the local state, but for the most part transfers everything to Redux. I didn’t quite understand in what cases it is more profitable to use the state react. I will be glad if you enlighten

Answer 1

The strategy is to give preference to the local state. I can say from my own experience that in most cases the global state is not needed. A typical case when a global state is used is authorization.

Answer 2

The data that is needed in several components is transferred to the editor.
In local states, usually only some flags remain that affect the display of the component itself.
