Understanding State in Angular

State in Angular applications can be anything like:

Router state

Component-local state

Shared state between components

In small applications, services are often enough for sharing data. However, as applications scale, several problems begin to appear:

Complex component relationships

Difficult state synchronization

Duplicate state across components

Unpredictable updates

Redux-style architecture solves this problem by introducing a centralized global store.

The store becomes the single source of truth for application state.
