This is full of weird examples. I take it it’s more useful for emulations than for use in any production environment. > Calling methods on a JavaScript class from Python code... This feels like an incomplete solution to a nonexistent problem. JavaScript and Python can communicate however you want them to over a Unix or IP socket, which will ALWAYS be much lighter weight than running layered interpreters this way. All you need to do is determine a communication protocol and implement a basic API. Send a command, wait, and listen for a result. > Wrapping a JavaScript function in a Python function... There are other ways to skin that cat. And most of them are better.
