I bet it is used in a lot of ways people don't notice. In my site[1] I use wasm to run an ancient piece of code called SGP4 to propagate satellite orbits, but it's totally invisible to the user. Someone actually ported SGP4 to JavaScript but it's slower and the results don't perfectly match the original, so it's great to have the option to run the real C version (actually the original is Fortran but the C port is the standard these days).

Ah, I used your site a lot after I bought a beginner's telescope some years ago, thanks for all the fun I had waking up early to spot satellites! Had no idea it had any wasm, interesting!
