I believe that Graal can (or soon will be able to) target both python and javascript. What I'm not sure about yet is whether you could write in python and output javascript. It may be that you would have to write in java and then you could output either python or javascript (see, e.g., https://www.graalvm.org/reference-manual/native-image/). That limitation would be a non-starter for me.
