What are actions in Redux?

Actions are the information payloads that send data from the application to the store. Actions are the only source of store information. Actions can be sent to the sore by applying the store.dispatch (). They represent Plain objects of JavaScripts. Actions are a type of property that states the type of actions that are being performed.

There is no need to define the constants of the action type inside a separate file. It is enough to use string literals for the action types.
