What Happened to WebAssembly

JS/TS interop, sure--but what are the use cases for running a JS runtime inside WASM?

Iirc, Shopify uses this to execute storefront code on the edge in a sandboxed environment.

People who want to write JavaScript for backend store functionality can, and then Shopify deploys that code into containers with small IO semantics

I believe Shopify looked into using a JS engine in WASM for front end sandboxing but ended up using a wrapper around the Shadow Realms API instead.

It's not front end sandboxing. It's edge function sandboxing. And they do indeed have this in prod: https://shopify.dev/docs/apps/build/functions/programming-la...

I've actually used Javy. Kind of interesting: https://github.com/bytecodealliance/javy.
