Code reviews and more code reviews. In both directions. Walk him/her through your stuff, explaining "why" as much as "what" and "how". Also, give your trainee a small coding task (ideally, one both simple and also similar to something you've walked them through). Review their stuff together, line by line, providing feedback as you go. Strive for some small wins they can build on to generate confidence. If there's an opportunity to refactor, that can be very instructive too. Also, take the time to sit w/ them and ensure their dev env is in good shape so the tools don't get in the way. Linters and the like can provide solid guardrails. Also, provide guidance on how to look things up (e.g. "mdn" search prefix, and bookmarks for your preferred reference materials). Finally, since your novice developer as yet has no bad habits to unlearn, strive for best practices in everything you do together (eg TDD; in fact starting w/ tests might be the best 1st step after the dev env is set up). /$.02
