/**
|
|
* This file includes polyfills needed by Angular and is loaded before the app.
|
|
* You can add your own extra polyfills to this file.
|
|
*
|
|
* This file is divided into 2 sections:
|
|
* 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
|
|
* 2. Application imports. Files imported after ZoneJS that should be loaded before your main
|
|
* file.
|
|
*
|
|
* The current setup is for so-called "evergreen" browsers; the last versions of browsers that
|
|
* automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
|
|
* Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.

* user can disable parts of macroTask/DomEvents patch by setting following flags

|
* will put import in the top of bundle, so user need to create a separate file
|
|
* in this directory (for example: zone-flags.ts), and put the following flags
|
|
* into that file, and then add the following code before importing zone.js.
|
|
* import './zone-flags';
|
|
*
|
|
* The flags allowed in zone-flags.ts are listed here.

* The following flags will work for all browsers.
|
|
*
|
|
* (window as any).__Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
|
|
* (window as any).__Zone_disable_on_property = true; // disable patch onProperty such as onclick
|
|
* (window as any).__zone_symbol__UNPATCHED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
|
|
*
|
|
* in IE/Edge developer tools, the addEventListener will also be wrapped by zone.js
|
|
* with the following flag, it will bypass `zone.js` patch for IE/Edge
