Angular 7 application gives error in IE 11 and works fine in all other browsers

Question

I have an application in angular 7 works fine in other browsers but fails to load in IE11

I have also added the below line from the source but still doesn't work for me.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Answer 1

In theAngular and Internet Explorer I un-commented the below import statement in polyfill.ts and it worked in IE11

import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

Initially the above lines were commented in polyfill.ts
