使用webpack 4示例实现热模块Repacement工作完美，我的react组件也可以平滑渲染 .

但是在最后的webpack文档中，提到了react-hot-loader .

Can any one explain the difference in HMR in webpack4 and HMR implemented using react-hot-loader ? Is there any difference when implementing react redux

reactjs webpack webpack-dev-server webpack-hmr react-hot-loader
