Roman Numerals

This is an AEC program that converts Arabic numbers to Roman numbers, compiled using my AEC-to-WebAssembly compiler.
This only works in very modern browsers. I'm not too interested in targeting archaic browsers here. This only works in Firefox 62 and newer or Chrome 69 and newer (those that support WebAssembly.Global). After a few years (if not months), all JavaScript environments will become as capable as they are, rather than like Internet Explorer.

You can see the source code of the AEC program here.
