Problem Statement
What is an action creator and why is it useful?
Explanation
An action creator is a function that creates and returns an action object, encapsulating the logic of creating actions and making the code more maintainable and reusable. Instead of manually creating action objects everywhere in your code, action creators provide a consistent way to create actions with the correct type and payload structure. They also make it easier to change action structure later since you only need to update the action creator function rather than finding all places where actions are created.
