React本机已具有异步存储。为什么我应该在我的react原生应用中使用Redux和Redux Thunk？

// 安装redux和redux-thunk
// npm install redux redux-thunk

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from './reducers';

const store = createStore(rootReducer, applyMiddleware(thunk));

// Action Types
const FETCH_DATA_REQUEST = 'FETCH_DATA_REQUEST';
const FETCH_DATA_SUCCESS = 'FETCH_DATA_SUCCESS';
const FETCH_DATA_FAILURE = 'FETCH_DATA_FAILURE';

// Action Creators
const fetchDataRequest = () => ({
  type: FETCH_DATA_REQUEST
});

const fetchDataSuccess = data => ({
  type: FETCH_DATA_SUCCESS,
  payload: data
});

const fetchDataFailure = error => ({
  type: FETCH_DATA_FAILURE,
  payload: error
});

// Thunk Action Creator
const fetchData = () => {
  return dispatch => {
    dispatch(fetchDataRequest());
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => dispatch(fetchDataSuccess(data)))
      .catch(error => dispatch(fetchDataFailure(error)));
  };
};

// Reducer
const initialState = {
  loading: false,
  data: [],
  error: ''
};

const dataReducer = (state = initialState, action) => {
  switch (action.type) {
    case FETCH_DATA_REQUEST:
      return { ...state, loading: true };
    case FETCH_DATA_SUCCESS:
      return { ...state, loading: false, data: action.payload, error: '' };
    case FETCH_DATA_FAILURE:
      return { ...state, loading: false, data: [], error: action.payload };
    default:
      return state;
  }
};

export default dataReducer;
