From the test lecture to this lecture, it was a really good lecture that felt like it was taught by a really good developer and a close older brother. I am a non-major (liberal arts major), but I always remember what the professor said in college about what makes a good article and a good answer. It was that it should be written from the perspective of the reader, not the writer. I always wanted to incorporate this principle into my code while studying development and preparing for employment. This lecture seems to have acknowledged that my thoughts were not wrong. At the same time, it is a really clear lecture that clearly shows me what I need to improve in order to become a better developer. This lecture is highly recommended to those who simply use Java, Kotlin, or other object-oriented languages and use Spring and think, "I'm developing in an object-oriented way." Or, if you feel that the SOLID principles and object-oriented principles that you studied before are not well applied to your code, I dare say that this lecture will really open your eyes. Not only the object-oriented part, but also the lecture title clearly answers what kind of code is easy to read. It contains a lot of helpful content for the collaboration process and the process of rereading previously written code. After listening to the lecture, I think I understand a little why developers have such a hard time naming. If you find naming too easy, you should listen to this lecture! ㅎㅎ The content covered in the lecture is, of course, excellent, and the explanations in each chapter are also very neat and easy to understand without any unnecessary details. I think it is a really, really good lecture. I highly recommend listening to it!
