That's actually a myth and real world performance isn't affected by this. See this video from leptos creator which is one of the more popular wasm ui framework https://youtu.be/4KtotxNAwME?si=D_vWV1LPQI-C9j8G
The biggest issue is actually the size of the payload since you need to ship the entire app and language runtime.
Also, a huge proportion of the list is just not understanding IEEE floats behaviour and blaming the language for it. Exactly like this post is doing. All those weird number things js does is because it only uses floats for everything and every language that uses floats will behave the exact same way.
Why would reshade be relevant? I don't get why without reshade is even worth mentioning?
