Ngrx/store Angular 12

Testability as @muetzerich mentioned already is also a benefit of using ngrx/store. Reducers are pure functions and those functions are easy to test, because they take an input and simply return an output and do not depend on properties outside the function and have no side-effects, e.g. http calls etc.

Ngrx is a group of Angular libraries for reactive extensions . Ngrx/Store implements the Redux pattern using the well-known RxJS observables of Angular 2. It provides several advantages by simplifying your application state to plain objects, enforcing unidirectional data flow, and more.

This data store connects to your components and services, and ultimately simplifies the entire process of data management in your Angular application.
