Ask HN: Intro to Programming Resources for Beginners

My wife is planning to do a bootcamp programming course. She's currently taking some prep course offered by the company and is progressing along doing various problems on a daily basis. This course is mostly independent studies where the instructor assigns problems with some lectures but you're expected to figure it most of it out on your own. You can ask questions and request help via a ticketing system but it's a little bulky to walk through. As I look through some of her solutions, I noticed she's a little deficient on some fundamentals (eg scoping, by value/reference concepts, etc.). They're learning programming using Javascript.

Obviously I can help her but I work during the day and she's taking some time off to focus exclusively on this pivot so I don't want her to sit around waiting on me.

Does anyone have any good resources (authors/books, bloggers, youtube instructors) that they like that has an easy to understand teaching style for beginners?

TIA
