I am a new front-end developer. Although there are simple HTML, CSS, and Python codes in the lecture, the lecture focuses on networks, so it would be good for those who have studied programming to some extent to take the course. It will be especially helpful for those preparing to become front-end/back-end developers or new web developers. This lecture was the most informative among Inflearn lectures. The explanations are easy to understand, and the smooth progress and diction are good, so I listened well even on the bus. ㅎㅎ I realized that it is important for front-end developers to be good at HTML, CSS, and JS, but it is also important to know network knowledge. By understanding the process of the code I wrote appearing in the browser, my perspective on errors and codes has broadened. The total lecture time is about 3 hours, so you can take the course without any burden. I recommend it to those who want to approach networks lightly and quickly!
