Many students who want to study programming will have studied from various books or blogs on the market. However, many of you may have felt that the learning speed was slow and that there was a lot of unnecessary content in the books or articles. 
Rather than focusing on the theoretical part, this lecture focuses on 'development' itself and only covers the core content of development.
