I'm 35 years old and hovering between "should I become a developer" and "maybe I'll just study it once." I graduated from a computer education department and learned Java, but I really couldn't understand "this." I'm the type of person who absolutely cannot move forward if I don't understand something, so I gave up back then. But now, watching this course, I understand it so well. Of course, there might be things I don't know that pop up later, but I'm leaving this review in admiration. There are many courses, but I'll keep going. Thank you.
