Maybe you don't need Rust and WASM to speed up your JS (2018)

(https://blog.feather.systems/jekyll/update/2021/06/21/WasmPe...) OP was very useful for us in optimizing our js vs wasm benchmarks. We were wondering what a very simple parallel problem like mandelbrot rendering would show about browser jits vs their wasm compilers.

Our conclusion was that wasm was consistent across browsers whereas js wasn't. Further, If you can use simd, wasm is faster. Also, v8 is way faster than spidermonkey.

Your link gives a 404, I think there is a problem with the path in the URL.

And since you are talking about the fastest mandelbrot on the web, here is my contribution https://mandelbrot.ophir.dev

It renders in real time and is fully interactive, all in pure js.

Does it still 404? Sorry I made some mistake with it. Theres a link in the post to an interactive demo.

The reason I said fastest is cause I wrote the hot loop with SIMD instructions. I'll be adding in period checking and stuff in a couple months time, will be sure to refer your work then, thanks.
