I worked as a developer, quit my job, and worked in a different industry for a long time. Recently, I wanted to go back to being a developer, so I took an introductory course. It was good because I could quickly hear only the key points because the unnecessary content was boldly omitted and the important content was explained based on practical work. I was burdened by starting again after a long hiatus, but the instructor explained it in an easy way and advised me that I could do well if I worked hard and consistently every time I lectured, which was a great help. I was so grateful for this lecture, and I will listen to the follow-up series and Spring. I am also looking forward to the database.^^
