Angular 6 - Why use @ngrx/store rather than service injection

Question

I am recently learning Angular 6 with @ngrx/store while one of the tutorial is to use @ngrx/store for state management, however I don\'t understand the benefit of us

Answer 1

There is also a 3rd option, having data in service and using service directly in html, for instance *ngFor="let item of userService.users". So when you update userService.users in service after add or update action is automatically rendered in html, no need for any observables or events or store.
