As far as I know, no one has ported JavaScriptCore to GNUstep. It might not be 
a huge amount of work but that last time I looked at it (ten or so years ago) 
the build system for JSC conflated a lot of things in the Apple paths that 
would need disentangling if you want the Cocoa bits but ELF and the Linux 
calling conventions, for example.

If you don’t care about performance, there are a couple of small JavaScript 
interpreters (jsQuick and DukTape) that would be fairly easy to bridge to 
Objective-C. I played with using DukTape and GNUstep ages ago and it looked as 
if it would be quite easy to add an implementation of the APIs that JSC exposes 
on macOS, but it would give around 10% of the performance.
