Angular is built on the latest standards of the web platform. Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers. A particular browser may require at least one polyfill to run any Angular application. You may need additional polyfills for specific features.
To support Angular in IE, open this file [metronic]/theme/angular/[demo]/src/polyfills.ts.
Uncomment all the imports under Browser Polyfills list and classlist.js
