初识redux

|src/
----|components/
----|store/
--------|index.js
--------|reducer.js
----index.js     

// src/store/index.js
import { createStore } from 'redux'  // 引入redux的createStore
import reducer from './reducer'

// 创建store
const store = createStore(reducer)    // createStore()方法需要一个参数：reducer
// 抛出store
export default store

// src/store/reducer.js
let defaultState = {
    inputValue: '',
    lists: []
}

export default (state = defaultState, action)=>{
    return state
};
