Actions are a fundamental part of state management and reactive systems. The @rx-angular/state library provides a powerful set method, but in certain scenarios, you might need to add specific behaviors to your user input or incoming events.

Typically, Subjects are used to implement this functionality. However, in larger applications, this approach often results in code cluttered with Subjects, leading to increased complexity.

That's where @rx-angular/state/actions comes in. It allows you to create observable action streams in a clean, maintainable, and less error-prone way, thus minimizing the amount of boilerplate code required.
