I don't think this is a good idea. It's easy to write JS once you have the basics of Java. Not the other way around. I find that the 'loose' nature of JS, combined with the very odd/unique prototype-chain paradigm makes for a ton of bad habits. When I refactored a project from JS to Typescript - beyond the obvious typing issues, I realized how poorly I was doing some things and was rather forced into a tighter compliance by the new paradigm, though not just a strictly typing issue. I think Java is a really great all round language for learning - you don't get caught up in some ugly things that C/C++ exposes, meaning you can 'get going' and learn concepts without the hurdles. Python might be another better learning language, in fact, maybe the best for algorithmic stuff.
