there's reddit and then there are all the in house enterprise-ish apps that basically amount to moving buckets of bits between cross-linked tables for which html+css is not cost effective.
Also, nobody wants to pay a C++ dev for doing a JS devs work, haha
you can still code in js or any other language.
I know.
I just thought, with JavaScript front-end development has been commoditized and C++ is harder than JavaScript. So I don't think many people would pay a more expensive C++ dev to use Qt for a WASM based app, if they could get it all going with a cheap JS dev.
It is more like "you can code in any language as long as it JS".
reddit would probably have an opensource rendering layer or third party uis that use it's api.
wasm will be the new android without the need to install apps.
The whole world of extensions that improve existing websites with additional buttons etc. is only possible because the page structure is exposed in the DOM. If Reddit were only WASM rendering on a <canvas>, there were no "Better Reddit" extensions.
