Polyfill does not seem to be working in IE 11

IE11 doesn't support class, you need Babel to transpile your code.

Oh, never ventured there since I've been only coding in vanilla for years. I'll look into how to do that, or if possible, code directly in a supported syntax/format.

Thank you.

you don't want to do that ... use babel to transpile your code 😉

Let's just say that I'm working with somewhat perverted legacy in-house framework that's been built for the past 20 years.

I don't know much 'bout Babel, but it's very difficult to get any preprocessors in there. 😓 But I'm gonna look into it on monday and see what's what.

[WebReflection]

If you can't get any preprocessor in there, you can forget about class, or anything related to modern JavaScript, as nothing will work in your target browsers ... or ... you use babel for the newer code you're writing

[WebReflection]

to expand, there's literally nothing I can do in here to make class or anything modern work in IE11, so this is your only chance https://babeljs.io/
