Considering developing practical web and software skills, I would want to understand a few concrete details before deciding what matters most. A small working project can reveal questions that a tutorial alone leaves unanswered. For Internetservice, I would use web development learning (https://internetservice.edu.pl/) as a starting point for a closer discussion of the subject. That is the part I would keep thinking about after moving on to something else. What would you build first to connect a new concept with something you can test?
