now VS jor1k

Technically you can run Node.js in the browser right now now.

Here is an example of downloading Node.js, extracting node executable, compiling to WASM to use node in the browser https://github.com/cemalgnlts/now.

Just to demonstrate how finicky folks on this r/learnjavascript are: I shared this Node on Web. Use Nodejs freely in your browser with Linux infrastructure. here and on r/node. r/node folks get it, that is, the work that had to go in to making that a reality. Folks on this r/learnjavascript evidently don't get the effort it took to make that so, after StackBlitz announced "... run Node.js, entirely inside your browser" only to walk back from that claim here https://github.com/stackblitz/webcontainer-core/issues/658#issuecomment-1091004244 "We currently do not expose a way to use WebContainer outside of StackBlitz.com".

For running programming languages other than JavaScript in the browser there is Emscripten and WebAssembly. There is v86, where a Linux build is compiled to WASM. Folks have written QuickJS into a Linux build compiled to WASM, Node.js into the Linux buildroot https://github.com/cemalgnlts/now, so Python or CPython can be written to the image and loaded into the browser as WASM as well https://github.com/pyodide/pyodide.

If the title is true, that would be a huge achievement. Unfortunately, the page says nothing about how it works and nothing about the speed advantage you get.

For my emulator jor1k [1] I tried something similar years ago [2]. However I haven't continued on this topic because of priority shifts. But the potential speed advantages are astonishing. My proof of context reached more than 1 billion emulated machine instructions per second.
