In React Redux, action creators are functions that create and return action objects. An action object is a plain JavaScript object that describes a change that should be made to the application's state. Action creators help organize and centralize the logic for creating these action objects.
Action Creators
Messengers with a Purpose: Action creators are like messengers in your app. They're responsible for delivering a message about what should happen next.
Instructions for Change: When something in your app needs to change, an action creator steps in to create a clear set of instructions, known as an "action."
Decide and Describe: Action creators help you decide what action to take and describe it in a way that your app can understand.
Easy Communication: They make communication between different parts of your app smoother by providing a standardized way to express intentions.
Initiating Change: Action creators as the ones who kickstart the process when your app needs to do something new or update information.
Action's creators in React Redux
Purpose: Action creators simplify creating and dispatching actions in React Redux.
Action Object: They generate action objects, which describe changes in the application.
Simplifies Dispatch: Action creators make it easier to dispatch actions without manually crafting every action object.
Improves Maintainability: Centralizing action creation in action creators enhances code maintainability, especially when action structures change.
Encourages Consistency: Action creators promote a standardized approach to action creation and dispatching throughout the application.
Example: Below are the examples of Action's creators in React Redux.
Install the following packages in your React application using the following command.

Create the folder inside the src folder i.e. actions, reducers, and constants.
Inside the actions folder create a file name todeAction.js.
Inside the reducers folder create a file name todoReducer.js.
