In that specific situation I find it very uncool. It's targeted only by C++, a language that is far too complex to have any business being used as a scripting language to make needles move on a virtual altimeter. You get all of the drawbacks with none of the benefits of a C++.
I don’t find it uncool at all. Well we have to start somewhere. Don’t you think this usage of WebAssembly is at least providing some feedback into it’s ecosystem to make improvements for next time? Id rather have developers choosing webassembly even if the implementation doesnt meet our expectations yet
