I ran EForth under the Subleq from Howe R.J at https://github.com/howerj/muxleq (the subleq one) first at QuickJS (trivial tasks, almost a 1:1 map from the C code, made in a hurry) and under... jsinterp.py from the infamous yt-dlp but using arrays instead of printing functions. But... if yt-dlp's "mini-JS" implements some captcha input functions... you can add I/O with ease and run EForth with what they call (not me) a "Not totally functional interpreter".

Not totally... until people there run the 110 rule program, Conway's Life, Subleq+EForth...

You may need to write a WebGPU shader and run it in a Beowulf Cluster to make that run fast!

I ran EForth under Muxleq (multiplexed subleq) under an n270 Atom (32 bits Intel) and was fast enough. Much slower than GForth or even PFE (which is slow compared to GForth), but usable even to do Algebra exercises. Rendering a Mandelbrot fractal (ASCII) lasted half a minute but it's amazing that few lines of C enable you to run a Forth with input composed of numbers. I even have a backup in paper.

I did some syntax changes for floats and that's it.
