Yes, that is exactly what you need. WebKitGTK+ historically did not provide
an API for JavaScriptCore, but it exports the same C API that is available
in other WebKit ports—so for example you should be able to reuse documentation
and most code from examples you can find for MacOS.

For a good starting point, you could use this tutorial:


Unfortunately Apple has retired the documentation for the JavaScriptCore C
API from developer.appple.com (they only have the Swift and Objective-C APIs)
there now. You can still read the JavaScriptCore C API headers installed
alongside the WebKitGTK+ ones; once you get a grasp of the basics they are
reasonably easy to follow.

I hope this helps.
