[gtzinos]

Hello, your demo at https://angular2-tree.readme.io/docs doesn't work.

Link works fine for me. Perhaps a transient outage?

Loads fine for me in both Chrome on MacOS and Safari on iOS. What browser, version, & platform are you using? What errors appear on the browser console?

It fails to load in IE11 with an exception:

SCRIPT5022: Exception thrown and not caught
polyfills.bundle.js (804,36)

Looks like a problem with polyfills. No idea why it suddenly started happening. Maybe need to include core-js polyfills as mentioned here:
angular/angular-cli#4128

All demos on docs page the seems to be broken on IE11, I'm getting error with "startsWith"

Fixed in docs. Thanks
Using the following polyfills:

import 'core-js/es6/string';
import 'core-js/es6/object';
import 'core-js/es6/array';
