The title "Javascript to Rust and Back Again" had me believing that this would be a tale of how Rust was abandoned in favor of Javascript! I'm so glad to see we

  At our local Rust meetup we have someone who's gotten WASM running on a microcontroller, so maybe that's not entirely unrealisitic. :P

    Wait, who was that?

      Maybe it was this guy: https://github.com/pcein/embedded-rust-workshop https://github.com/pcein/embedded-rust-workshop

      This is somewhat related, although embedded here means embedding interpreted WASM into a CLI application. Similar method might be doable on an MCU. https://fosdem.org/2018/schedule/event/rust_embedding_wasm/ https://fosdem.org/2018/schedule/event/rust_embedding_wasm/ Then there's "WebAssembly interpreter in C": https://github.com/kanaka/wac https://github.com/kanaka/wac Looks like it might be good enough for implementing WASM "scripting" support in smallish environments.

        https://crates.io/crates/parity-wasm https://crates.io/crates/parity-wasm is an interpreter in Rust; there's some really interesting stuff happening with it in various forms. One of the most... extreme is https://www.reddit.com/r/rust/comments/88sxah/nebulet_can_now_call_external_functions_from_wasm/ https://www.reddit.com/r/rust/comments/88sxah/nebulet_can_no... (There are some more production-aimed things as well.) I think this idea has a lot of merit, overall, exactly as you say: kind of like a Lua.
