This whole thread is confusing. The blog in the OP, the comments section of which are you posting in right now, is literally about adding WebGPU support to a headless JavaScript interpreter Deno, that includes no HTML/CSS/DOM/Windowing engine. WebGPU is a standardized API built on platform specific graphics APIs, it is not a "renderer". The WebGPU support is based on wgpu, which isn't used in Chromium; it's actually the basis of Firefox's WebGPU implementation (and widely used by most Rust WebGPU projects, such as Bevy.) The person you are replying to simply wants native windowing APIs added to Deno as well, which has been done about 1,000,000 times in various other languages.

I'm very confused because every comment you have posted in this reply chain makes no sense in the context of the actual blog.
