所以我正在學習如何使用 redux 和 redux persist，目前我遇到了一個問題。每當我嘗試映射我商店的內容時，它都會拋出一條錯誤消息TypeError: tasks.map is not a function，我真的不知道為什么會出現這個問題。我用谷歌搜索并嘗試調試它，也嘗試重寫代碼幾次，但都無濟于事。這是我的全部代碼：rootReducer.jsimport React from 'react'let nextToDo = 0;const task=[    {    }]const reducer =(state=task, action)=>{    switch(action.type)    {        case 'add':            return[                ...state,                {                    name: 'new',                    id: nextToDo+=1                }            ]        default:            return state;    }}export default reducer商店.jsimport reducer from './rootReducer'import {applyMiddleware,createStore} from 'redux'import logger from 'redux-logger'import {persistStore, persistReducer} from 'redux-persist'import storage from 'redux-persist/lib/storage'const persistConfig ={    key: 'root',    storage}export const persistedReducer = persistReducer(persistConfig, reducer)export const store = createStore(persistedReducer, applyMiddleware(logger));export const persistor = persistStore(store);export default {store, persistor}索引.js：import React, {Component} from 'react'import {createStore} from 'redux'import reducer from './rootReducer'import 'bootstrap/dist/css/bootstrap.min.css'import {Button} from 'react-bootstrap'import {store} from './store'import {connect} from 'react-redux'class Index extends Component {    render(){    const {tasks} = this.props    const add=()=>    {        store.dispatch(            {                type: 'add',             }        )    }    store.subscribe(()=>console.log('your store is now', store.getState()))    return (        <div>            {tasks.map(task=><div>{task.name}</div>)}            <Button onClick={()=>add()}></Button>         </div>    )}}const mapStateToProps=(state)=>{    return{        tasks: state    }}export default connect(mapStateToProps)(Index)
