The entire state of the application is stored in an object called Redux Store. We can create a Redux Store using the configureStore function imported from @reduxjs/toolkit:

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

In the configureStore function we pass an object containing at least one reducer. The store is a reference to the create store. We can access the object containing the state data using the getState method:

console.log(store.getState())
// {countValue: 7}
