IE11 completely deprecated in v6?

[bmueller-sykes]

There's a note at the end of the v6 release notes that IE11 is deprecated. It's not clear from the note whether an external polyfill will make the v6 version of this library work in IE11, or if IE11 is just completely unsupported going forward.

I'd love to bail on IE11, but alas there are plenty of corporate environments that still rely, and will continue to rely, on that browser.

version 6 of react-markdown?
Both transpiling and polyfills would be needed. Babel preset env can take care of both https://babeljs.io/docs/en/babel-preset-env

So if I have this in my package.json file, based on that documentation, then I should be good?

  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie < 11",
    "not op_mini all"
  ]

$ npx browserslist ">0.2%, not dead, not ie < 11, not op_mini all"

Oh cool! I didn't know that feature existed
