What is the advantage of Feature State NgRx?

Question

Angular

Why declare in each feature module StoreModule.ForFeature()instead of /appjust creating a folder in a folder, for example /app/store, where to separate the states by domains? for example

-app
--store
---user
---products

What is the advantage of dividing the store by features? All the same, the same user State will obviously be used not only in the user feature, but throughout the application? I actively read the documentation until I could find an explanation, unfortunately

Answer 1

Just an encapsulation of logic.
Although there may be something else, but if the docs say nothing about it, then no.
