it's not that related, I like to create compilers/transpilers/weird languages, see the "Language Projects" section here: https://marianoguerra.github.io/

But there's a relation, two years ago I prototyped a thing that tried to make a headless version of instadeq that could run in the browser and the server, the idea was a dataflow language where the data was represented as apache arrow tables where filters and transformation expressions where compiled to wasm. The prototype kind of worked and I had a lot of fun, I thought about sharing the fun by writing a small book about creating 10 toy languages that compiled to Wasm, I shared the idea with Patrick, he said he was thinking about something similar and the idea evolved into the current book.

In-browser data analysis is a great place to use Wasm. Javascript is great, but larger datasets really benefit from SIMD + tighter memory control/controlled memory layouts.

Some interesting data-related Wasm projects:
