IE 11 support No longer available in Angular 13

If your application was supporting IE13, then upgrading to Angular 13 might not be a good choice for you.

Officially Angular has removed support for IE 111

You can find more details here Angular – Update Angular.

The worldwide usage of Internet Explorer 11 (IE11) has been steadily declining for years, and is currently at 0.73% according to StatCounter and 1.70% according to NetMarketShare, meaning that a very small fraction of the overall world population uses this browser

How do we benefit by removal of the support ?

• Application users
  • the apps will be smaller and load faster thanks to the removal of IE11-specific code
  • the use of modern Web APIs will result in further UX improvements

• Application authors and stakeholders
  • will benefit from improved APIs and build infrastructure
  • will reduce the risks and liabilities due to known security issues and limitations of IE11
  • can lean on our decision as an argument when talking to application stakeholders about IE11 support (if they still support it)

Support for below can be added

• CSS Variables, Intersection Observers, CSS Grid (components/issues#7374)
• Native version of EcmaScript APIs (e.g. regexp)
• Web animation APIs
• Proxies
• etc

On August 17, 2020 Microsoft announced deprecation of IE11 support in Microsoft 365 apps and services, with the removal date set for August 17, 2021. Microsoft Teams already removed support for IE11 on November 30, 2020.

Happy coding by upgrading your projects to A13. But just a word of caution, ensure to thoroughly do your homework before you kickstart this project.
