You’ve been a good developer. You are using the Angular CLI for your projects in its purest form. There isn’t a super custom build process. Application development has been going along well and then you get the email, “Hey the site won’t load in IE11?”

Frantically you open up the site in IE. Nothing. You see a console error, and you think that isn’t in MY code. Ages go by as you  mentally search through the code trying to figure out where you may have put some code that could be incompatible with IE. You remind yourself that Angular itself says that they work with IE11.  Finding nothing you go to the internet.

You read this Stack Exchange article and breathe a sigh of relief. I just forgot to add in the heavy poly fills. Once again you mutter about how you cannot wait until IE finally dies.
