Hello. I am a first-year junior backend developer. I was studying the front-end field due to the company's needs and personal desires, and I happened to come across this course, so I purchased it and am currently taking it. It definitely felt unfamiliar at first because the flow was different from the back-end field, but it is getting more and more interesting and faster because it teaches the principles and usage of the language called JavaScript. It is better because it is a method of studying while creating things together rather than just learning the principles, so even when I don't understand it well, I can learn by touching this and that on my own. Thanks to the good curriculum, after listening to all of these courses, I expect to be able to achieve the position of a back-end developer who can understand the logic of the front-end at least. Thank you for the good course.
