| OP links to a not quite informative web site.

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

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

| Also, SerenityOS's creator has a great channel:

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

| His meticulous approach of implementing specifications by

| me to adopt the same style.

| It would be nice if LibJS would become an independent library,

| 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.

| Jeez...

| What is the draw here compared to other JS engines (either

| quickJS/duktape on the small end)?
| gigel82 wrote:
| 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.
| orbifold wrote:
| To be fair both JavaScriptCore and V8 heavily rely on the
| base C++ libraries that are part of Chromium and Webkit.
| gigel82 wrote:
| You can totally build and use V8 independently (many
| projects, including node.js, do it) and they have
| documentation specifically targeted at embedders.
|
| JSC is not as nice but can still be built and embedded as a
| stand-alone library.
