I'm personally a big fan of Frontend Masters: https://frontendmasters.com. I've found it to be one of the most comprehensive resources for web development out there, especially for front-end work. I think it's a great starting point for any prospective web dev, especially if you're keen on learning some crucial JS concepts.

Once you dive a bit into the fundamentals, you can also check out Wes Bos's suite of courses: https://wesbos.com/courses/. His React tutorial is definitely my favorite one out there.
