bookStore Dispatch Method

Redux store object has a dispatch method which can be used for dispatching actions.

When we want something to happen, for example, the counter value to be incremented, we can dispatch the counter/increment action using the dispatch method:

import { configureStore } from '@reduxjs/toolkit'
const store = configureStore({ reducer: counterReducer });

// The action object can be directly created inside the method call
store.dispatch({ type: 'counter/increment', amount: 7 });

// Or it can be passed using a reference
let incrementAction = {
  type: 'counter/increment',
  amount: 7
};

store.dispatch(incrementAction);

The reducer function will handle this dispatched action we passed into the Redux store, counterReducer. The reducer function returns a new state object and updates the store accordingly – we don't have to do anything related to that; it is handled by Redux and happens on the backend, we dispatch the action using the store's method.
