If you want to see some good videos of Linus Groh developing libJS, check out his YouTube channel: https://www.youtube.com/linusgroh

Also, SerenityOS's creator has a great channel: https://www.youtube.com/c/andreaskling

I, too, enjoy Linus's YouTube channel! :^)

His meticulous approach of implementing specifications by writing code interleaved with quotes from the spec has inspired me to adopt the same style.

It would be nice if LibJS would become an independent library, but last time I checked it had way too many dependencies on other core / helper libraries in SerenityOS for it to be ripped out; not sure why it would need a separate website unless making it independent is in the plans.

Being closely integrated with the rest of the system & libraries is a feature, not a bug - no plans to change anything about it :^) That being said, it's definitely possible to use it outside of SerenityOS as a regular library, just need a checkout of the serenity source for that. See https://github.com/linusg/libjs-test262 for an example, specifically the CMake files and `src/main.cpp`.

The separate website is just to have a nice & short link to the test262 graph and whatever else we'll put there eventually; and also because it's built/deployed in a slightly different way than the main serenityos.org website.

Will LibWeb get its own site too?

Oh for fucks sake people. There seems to be 5 lines of text on that page and to see them I needed to turn off content blockers. Jeez…

Use a browser that let's you disable JS by default and whitelist websites where you have no choice.

It's your "content blocker" that's broken if it's blocking random stuff. It's a very simple website without weird things.

This would be a better link: https://github.com/SerenityOS/serenity/tree/master/Userland/...

OP links to a not quite informative web site.

That's not much better to be honest. No readme.

oso2k2• 4 years ago

True. Looks to be a little tightly coupled to the OS for the moment.

What is the draw here compared to other JS engines (either v8/JSC/spidermonkey on the big end or something like quickJS/duktape on the small end)?

gigel823• 4 years ago

All those other engines are cross-platform, whereas LibJS is UNIX only and actually very dependent on SerenityOS libraries (so not really a portable UNIX library), but that's apparently the intended design.

To be fair both JavaScriptCore and V8 heavily rely on the base C++ libraries that are part of Chromium and Webkit.
