Pick one of the wasm runtimes written in JS listed at https://github.com/appcypher/awesome-wasm-runtimes and find out =)

No idea, but according to this site: https://github.com/appcypher/awesome-wasm-runtimes there a wasm runtimes written in all kinds of languages. This does not appear to be a very challenging thing to do, but I haven't look at this closely.

Firecracker is a fine technology, but serverless companies have started taking advantage Wasm's faster start-up and invocation times for use cases of running Wasm on the server (https://www.youtube.com/watch?v=yqgCxhPAao0). The deny by default security policy makes Wasm a popular choice to run code in isolation, particularly for maximizing hardware resources in the multi-tenant environments these serverless companies operate. > Is there a good reason to do this? One use case to run JS inside a Wasm VM is Shopify Functions. Shopify allows their customers to customize things like checkout flow by writing code compiled to Wasm which gets executed during the checkout process. They want their customers to be able to write JS as well as other languages. https://github.com/Shopify/function-runner > I thought WASM typically used the V8 JavaScript

Yeah, this is one of many non-browser runtimes, e.g. see https://github.com/appcypher/awesome-wasm-runtimes Lunatic is more opinionated than most of these or node, though, in that it's trying to emulate a particular concurrent system design pattern borrowed from Erlang/BEAM.

It depends on your needs. This awesome wasm list also is confusing. https://github.com/appcypher/awesome-wasm-runtimes

Wasm is far from browser-bound; there are many standalone runtimes and they're used for lots of different things, one of the big ones being edge-workers. Here's a collection of runtimes: https://github.com/appcypher/awesome-wasm-runtimes

I spent the whole day yesterday (~16 hours) doing various wasm demos in rust, python, typescript to evaluate its suitability in an upcoming project that I am planning. All I can say re:wasm /bytecodealliance is wowwee! so many runtimes, so many platforms and intermediate formats. Bindgen macros in rust is imho one of a hundred reasons to learn and love rust. Really was impressed by the ability to obviate oci containers was slick. Here is a comprehensive list of wasm runtimes : https://github.com/appcypher/awesome-wasm-runtimes

https://github.com/appcypher/awesome-wasm-runtimes quite a list, it is becoming a new JVM that runs all different languages.

Firefox's WA backend does streaming compilation (i.e. compiling bytecode directly to machine code while it's still coming off the wire) for Tier 1, right now, by default, today. Afaik, WA is the first mainstream vm isa that it's even possible to do this. Do you know of any other VM that can compile its bytecode in one pass that is on by default? I'm genuinely interested. https://wingolog.org/archives/2020/03/25/firefoxs-low-latenc... But this whole discussion is out of scope for your use-case. If it's For Fun (tm) that's one thing, but (presumably) this is a practical integration into an existing language. Why are you implementing a VM instead of integrating an existing implementation? Certainly you wouldn't even consider implementing a custom from-scratch implementation of the JVM, the fact that it's even possible to attempt such a thing

Numerous native runtimes for webassembly already exist[0], with the current popular choices apparently being Wasmer[1] and Wasmtime[2]. All one would need to do (AFAIK) is ship a client for all major platforms, as is done with Electron (and web browsers themselves, and everything else.)

That's entirely dependent upon the runtime. Wasm is advertised as many things it's not. The only thing it is, is a set of instructions. Here, go through the list. https://github.com/appcypher/awesome-wasm-runtimes
