- I didn't look for JS to Python tools - https://www.amazon.com/s?k=javascript+and+python listed a few books that may be helpful; though I'm not sure if any are open source / Creative Commons
- "Think Python 2e: How To Think Like a Computer Scientist" could be ported to Python and JS (and/or translated). https://greenteapress.com/wp/think-python-2e/ - There'd need to be some sort of way to display the comparative code samples as grouped together but not with tabs.
