redux combineReducers 的使用和注意方式

学习代码的时候，一定要动手实践，否则根本学不会！

import { createStore, applyMiddleware } from "redux";
import { combineReducers } from "redux"
//引入中间键盘
import logger from "redux-logger"
import thunk from "redux-thunk"

// 两个reducer 我开始测试 combineReducer
function nameReducer(state = { "name": "action" }, action) {
    const type = action.type;
    switch (type) {
        case "get":
            return state;
        default:
            return state;
    }
}
function CountReducer(state = 10, action) {
    const type = action.type;
    switch (type) {
        case "add":
            state++;
            return state;
        case "minus":
            state--;
            return state;
        case "asyncAdd":
            // 我打印这个就是想看下，它咋接收参数的！
            console.log(action);
            state++;
            return state;
        default:
            return state;
    }
}


// applyMiddleware 使用中间键
const store = createStore(combineReducers({
    count: CountReducer,
    name: nameReducer
}), applyMiddleware(logger, thunk));
export default store;
import { cre
