Is something like this possible for IE11?

Stupid question: Is something like this possible for IE11? Or does it exist already?

I don't use IE for internet browsing, but testing localhosted web applications or draft build websites, to try and ensure compatibility. Most stuff breaks in IE11 these days, and I got to thinking "polyfills would probably make it work", but my searches haven't found any.

Not a stupid question. It's likely possible as an IE add-on, but since IE is not used as much nowadays I don't think the focus has been there in terms of polyfilling stuff.

Many of the same polyfills are probably relevant, but each browser has a different way of writing extensions so it just needs someone familiar with IE add-on development.

On a personal note, if you are using IE to test compatibility though, I think it and of itself does a fine job. I make sure that all my sites work in IE, without any modifications. Likewise, they also work in older browsers without polyfills. So ensuring sites work in IE with an add-on is not really representative of the user base, as most IE users won't have such an add-on and the best policy is to not use incompatible JS in the first place. Polyfills and transpiling have always been a last resort.
