After a long time, I took the lecture because I had time, and I feel like my head is very organized. Everything was perfect, but I would like to give my opinion because you said you appreciated the feedback in the last lecture. Spring is the main topic, but if you could share some practical knowledge and experiences outside the topic, it would be very helpful. For example, 1. Differences depending on the Java version 2. Architecture that can change depending on the server and infrastructure 3. Practical comparisons and pros and cons with other frameworks and languages besides Spring~ Thank you for your help.
