What To Expect When You're Expecting To Drop IE11

So you've decided to drop support for IE11 and move onto evergreen browsers only (as of mid-2019, IE11 is only about ~2% globally). That's great! ๐ŸŒฒ

With that in mind, here's a giant list of the features you should use, safely, without polyfills or feature detection. ๐Ÿ“ƒ

Before we start, of course, there'll always be old browsers. And, to be fair, browsers in emerging markets are more complex: like UC, KaiOS (based on an older Firefox), and Opera Mini. In these cases, I suggest serving no JS whatsoever (if possible), or encouraging users to upgrade. ๐Ÿคท

Let's go! โฌ‡๏ธ
