javascript - 下面这个reducer，不用combineReducers是可以运行的，为什么用了就不行，也没报错，就是没有效果？

Question

import { combineReducers } from 'redux';



function reducers(state = {
  text: '你好，访问者',
  name: '访问者'
}, action) {
  switch (action.type) {
    case 'change':
      return {
        name: action.payload,
        text: '你好，' + action.payload
      };
    default:
      return state;
  }
};



const reducer = combineReducers({
  reducers
  
})

export default reducer
