graaljs VS ChakraCore

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

I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:

https://github.com/chakra-core/ChakraCore

Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

The JS engine is open source: https://github.com/chakra-core/ChakraCore

ChakraCore

Not to forget the engine Charka: https://github.com/chakra-core/ChakraCore

The only bit of the old Edge that had its source emancipated. It was/is? quite performant.

As a Linux user, I very much think Microsoft should have continued Trident and Chakra. Apple also should have continued releasing Safari for Windows. Our web QA setup was entirely built around Macs back then, but it was great to be able to test sites with Safari on Windows, and to have another responsive browser on Win32.

Edge was initially using Chakra but has been rebuilt using Chromium and the V8 engine.

https://github.com/chakra-core/ChakraCore/wiki/Architecture-...

I've found the source code to be quite readable too - albeit from a bug-finding perspective, not a strictly pedagogical one.

Furthermore, the new architecture decouples the JavaScript interface from the engine, enabling the use of other JavaScript engines such as Hermes, V8, or Chakra.

ChakraCore

I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: https://github.com/chakra-core/ChakraCore. But it looks like it’s still chugging along as a community effort rather than being completely abandoned.
