Instead of one action, useReducer in ReactJS is dispatching two distinct actions.

edit

This statement is not correct as useReducer in ReactJS can dispatch any number of actions depending on the implementation. The dispatch function in useReducer takes an action object as an argument and updates the state accordingly. It is up to the developer to define how many actions to dispatch and what their effects will be on the state. The useReducer hook is a powerful tool in ReactJS that allows for complex state management and can dispatch any number of actions to achieve the desired result.
