This is a Spring introductory course that really fits the title. I think I got a taste of what Spring is and why many companies are adopting it. Now, I will start from the core principles of Spring and learn what it tastes like and how to cook it. I started in January as a non-major and finished the Java language with Java Basics for a month and a half, and started studying backend development with Spring Introduction in mid-February. Since I am still not familiar with Java grammar in practice, it was hard to keep up with the member management example and I didn't understand it well. If you look at the course reviews, there are quite a few non-majors who had difficulty understanding like me. After finishing a large chapter, I studied Java grammar that I didn't understand well through YouTube or books, and organized theories that the instructor mentioned in passing (such as GET and POST concepts) by Googling them. By interpreting the code line by line and watching the lecture again, I was able to understand the intention and purpose of what the instructor wanted to teach. By doing this, I was able to accelerate my understanding time as I went to the next lecture. The total lecture volume is about one day, but I think I listened to it for about a week. It took me longer than others, but I think I learned it well until the end. If there are non-majors like me, even if you have difficulty understanding Java grammar or the lecture, I hope you don't get discouraged and keep learning until the end because it took me this long to learn it, but I learned it well in the end. I think we haven't learned enough yet to judge whether we are suitable for development or not because of the difficulty of this lecture. You can finish it. There were many parts that were difficult while studying development on my own, but thank you for creating such a great lecture. Now that I've taken the first step, I will definitely finish it until the end and get a job as a backend developer, even if it's slower than others. Thank you.
