> is I'm allergic to Go and just use Rust 99% of the time these days

I confess I have not used Go. I am allergic to Typescript, let alone, Javascript, and Node.js should be deleted.

I do mostly real-time audio, so I too am Rust (job control in Shell). But what decent choices are there for garbage collected systems?

And garbage collection, for most systems, is crucial

I guess you could use OCaml / ReasonML now, the latter especially feels like Rust with a GC.

Leptos etc. WASM is mature enough to just go for it. Same code sharing arrangement as using TS on the backend but using the backend language on the frontend instead.
