Polyfills 的几行代码使您的应用程序与不同的浏览器兼容.我们编写的代码主要在ES6(新功能:概述和比较)中，与IE或firefox不兼容，并且需要一些环境设置才能在这些浏览器中查看或使用.

Polyfills in angular are few lines of code which make your application compatible for different browsers. The code we write is mostly in ES6(New Features: Overview and Comparison) and is not compatible with IE or firefox and needs some environment setups before being able to be viewed or used in these browsers.
