It was a cost-effective lecture, and I learned a lot because the content was rich. There are many more expensive lectures that just teach you how to create APIs, but there are also many lectures on error handling, how to set up JWT tokens without security, etc., so I can't count them all, but I think it organized the content that people who are new to Spring want to know in a broad sense! Thank you. - It's great for creating boiler templates, but it's also very helpful for learning the basics of Spring ^^
