Angular 4 application crashes in IE11

Question

My Angular 4 application crashes in IE11 right at the application load.

Here is the error that I get:

Here is where the exception link takes me to in the IE's debugger:

Any ideas why this would be happening?

IE version: 11.0.9600.19003

Angular version: 4.3.6

Have you included/installed the polyfills? angular.io/guide/browser-support#polyfills — Ludwig

Because IE doesn't support "For_of"

Go to polyfill.ts

Un-comment all "import" lines under /** IE9, IE10 and IE11 requires all of the following polyfills. **/ and /** IE10 and IE11 ....*/
npm install --save classlist.js npm install --save web-animations-js
