I am a 10-year developer. I didn't start this job because I liked development or because it was a good fit for me, but now I hope to retire from this job. For me, who had no basic foundation, it was difficult to keep up with the work, and I always regretted that I didn't have a better basic foundation. Even as my experience grew, it was difficult to go to job interviews or solve basic problems. I want to fulfill my wish of building a solid foundation by following the instructor's roadmap! Thank you for the great lecture!
