推荐答案

Polyfills 在 angular 中是几行代码，使您的应用程序兼容不同的浏览器.我们编写的代码大多是 ES6(新特性:概述和比较)，不兼容 IE 或 firefox，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.

Polyfills.ts 由 angular 提供，可帮助您无需专门设置所有内容.

Polyfills.ts was provided by angular to help you do away with need to specifically setup everything.
