For JavaScript, all the underlying work used for Deno is pretty much done. I'm not sure if a more complete example. Though Lua probably has lots of good and feature rich examples as well. Can't speak at all to Ruby or Python integrations. In the end, I'd suggest it depends on your audience and what existing skills or biases they're likely to bring to the table. My one warning is that I've used software that integrated JS and it hasn't aged well. From the Adobe products with ExtendScript to other, older and incompatible JS engines before ES5 even, don't get locked into something difficult to update and keep current.
