import React from 'react';
import ReactDOM from 'react-dom';
import { createStore } from 'redux'
import { Provider } from 'react-redux';
import App from './containers/App';
import todoApp from './Reducers/Reducers';

let store = createStore(todoApp);
let app = document.getElementById('app');
ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  app
);

这代码为什么是语法错误?
