ts-loader: convert typescript (es6)to javascript (es6)
ts-loader：转换typescript (es6)为javascript (es6)
babel-loader: converts javascript (es6)to javascript (es5)and Typescriptdoesn't do polyfills, which babeldoes. If you write client-side code in es6and want it to run on modern browsers, you'd probably need babel's polyfills.
babel-loader: 转换javascript (es6)为javascript (es5)并且Typescript不做polyfills，babel确实如此。如果你写的客户端代码es6，并希望它在现代浏览器上运行，你可能需要babel的polyfills。
It is less justified with server-side code - just use the latest nodeversion for es6support. But babel still provides some goodies that tscdoesn't - like caching, or a huge range of plugins that can be very useful.
服务器端代码不太合理 - 只需使用最新node版本即可获得es6支持。但是 babel 仍然提供了一些tsc没有的好东西——比如缓存，或者大量非常有用的插件。
It's not necessary but a practice for using them all together.
这不是必需的，而是将它们一起使用的练习。
