I am currently working as a front-end engineer :) When I first joined the company, there were many parts where it was difficult to ask questions or get advice because there was no mentor. However, after listening to this lecture, I was able to write good-looking code and clearly understand why it should be done that way. As mentioned in the introduction, it is not a lecture that cannot be understood even if you do not know the Java language, and it was easy to read and understand because it easily explained the core contents covered in the Clean Code book. I highly recommend it to those who are about to join the company or want to write good-looking code!
