Converting createStore to configureStore

Show a side-by-side code example that transforms a Redux store initialization from createStore to the Redux Toolkit's configureStore method.

import { createStore, applyMiddleware } from 'redux';
import rootReducer from './reducers';
const store = createStore(
  rootReducer,
  applyMiddleware(...middlewares)
);

This is the original way to initialize a Redux store using createStore with middleware applied.

import { configureStore } from '@reduxjs/toolkit';
const store = configureStore({
  reducer: rootReducer,
  middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(...middlewares)
});

This is the refactored way to initialize a Redux store using the configureStore method from Redux Toolkit with middleware applied.
