Reactjs 15.4.X IE11 Objects are not valid as a React child

Reactjs 15.4.X 在IE下出现如下异常：

Objects are not valid as a React child (found: object with keys {$$typeof,type,key,ref,props,_owner,_store}). If you meant to render a collection of children,use an array instead or wrap the object using createFragment(object) from the React add-ons. Check the render method of `CoreLayout`.

解决办法： 将 babel-polyfill 在import react 和reactDom之前引入即可。

• babel-polyfill
• react
• react-dom
• webpack 参考如下配置：

entry: [
   'babel-polyfill',// Load this first
   'react-hot-loader/patch',// This package already requires/loads react (but not react-dom). It must be loaded after babel-polyfill to ensure both react and react-dom use the same Symbol.
   'react',// Include this to enforce order
   'react-dom',// Include this to enforce order
   './index.js' // Path to your app's entry file
]
