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