graaljs VS hermes

I would guess that depends on the licensing context in which it will be running, since Rhino is MPLv2 <https://github.com/mozilla/rhino/blob/Rhino1_7_14_Release/LI...> and OP's repo is MIT whereas Graal is UPLv1 <https://github.com/oracle/graaljs/blob/graal-23.1.2/LICENSE>. GitHub's license gizmo claims it is OSI/FSF approved, but Oracle gonna Oracle and they for sure have more lawyers than you do

graaljs

Here: https://github.com/oracle/graaljs

It's by Oracle: https://github.com/oracle/graaljs; seems to be built to interop w/ GraalVM based languages/services

If you need you can run JavaScript from within Java using Graal.js or Nashorn. To evaluate dynamic user input (Strings) you could also use a ScriptEngine (e.g. JavaScript) or dynamically compile inputs to Java using the JShell API.

That's just incredibly cool, my congratulations!

Foremost, my apologies if this is a nonsensical question. I haven't been soaking in the WASM ecosystem enough to know how much WASM is "just" JS versus ... something else.

Caveat aside, I saw one of the commits mention jython, which notoriously has ancient (and probably incredibly incomplete) python 2.x support; do you know if python-wasm would run on top of GraalJS (https://github.com/oracle/graaljs#nodejs-support)?

Separately, do you want issues related to zython.org in the cowasm issue tracker? It returns 405 (method not allowed) over and over on POST https://zython.org/python-wasm-sw/read-signal for me

Must be a fork because I found my own commits haha

Hermes is a big one as well: low startup latency, low memory

Hermes

InstagramBundle.js.hbc.spk.xz is likely a compressed version of Hermes bytecode (js.hbc)"

In React Native's case, it uses an engine called Hermes:

📜 I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.

For me it’s a JS engine for React Natve - https://hermesengine.dev/

💉 Building and injecting a JS bundle a basic concept: If the native code wasn’t changed, simply create JS bundle and inject it into the precompiled application. (You must take an extra step to convert a js file to bytecode if you use the Hermes js engine.)
