I just did a duckduckgo search and found this. https://github.com/coracle-social/ostrich-script-js. I'm planning to provide tools for my users to pass around a wink nlp compatible bayes filter model via nostr private messages. The file size (of the model) is too big, so I'm planning to chop it up into multiple private nostr messages. I don't see how using lua or wasm helps and my javascript approach is more-or-less working, but I'm in a position to change course if I'm wrong.
