junuuu's honest review, Real-world! Developing a library management application with Kotlin and Spring Boot (Refactoring a Java project) course

I am writing a review after listening to half of the lecture. I will be working at a company that I will be joining soon and I happened to come across Kotlin through jojuldu's recommendation, but I think I am learning a lot. I think there are many people who have worked on test code, Enum, fetch join, and QueryDSL while working on personal projects, but there are many things to learn from the instructor's coding style, so I recommend it. And you can learn how to apply theories such as Kotlin's extension functions in this way. Also, the instructor is very kind in giving answers. I haven't listened to Kotlin Introduction for Java Developers yet, but I definitely want to listen to this lecture later. Thank you for the quality lecture~
