Answer 1

The problem with learning is not finding a good presentation in a video or a book. The problem is to find a good teacher who will proofread your texts. do a review.
Learning to write is not difficult, it can be easily done on your own. It is much more difficult to develop a good style, clear and expressive both at the level of variable names and the structure of the entire program. Live interlocutors and critics are needed here.
It is unfortunate that many of the courses that advertised themselves as reviewed courses lost quality after the influx of clients. Reviews confirm this. (naturally on independent sites.)
Sorry, but I can’t advise just such courses, but at least I indicated the direction in which to look.
At the same time, I advise you to read books on the topic of clean code, refactoring. The habit of clean code must be developed immediately, otherwise there will be discomfort in retraining.
When the programs become more or less complex, you can turn your attention to TDD.
The answer turned out not specifically on the topic, but I hope it will be useful. Good luck.
