One of the instructors considered to offer the most cost-effectiveness in Inflearn is Coding Works. Recently opened courses are a bit pricey because they are cutting-edge technologies, but looking at the existing content, I was impressed by the low tuition and the vast volume, so I found Coding Works and took the course. Even if you go to an offline academy, it is hard to find a class density that boasts such a vast volume, and if you look at the entire lecture structure, the content is so detailed that the lecture time exceeds 40 hours. In addition, it is a class that focuses on practical training by integrating the latest intermediate and advanced technologies of Webpub, so you can obtain results that cover all of the actual advanced technologies. Above all, the instructor's response was very impressive. I had an inquiry on Sunday, so I left two questions about the course, and they were answered right away that day. There is no reason not to recommend this course with its vast volume, the latest technology-intensive practice, and the instructor's quick feedback. I honestly think that web publishing skills are basic for front-end developers before React and View. These days, boundaries between industries are collapsing and multi-tasking is required, so those who know how to do everything can get high salaries. Those who need to be able to create what's in their heads at least as much as screen implementation, I recommend that those studying React or View take this course on their own. It's not yet complete, but the explanations are so kind and good that studying is fun^^ The vast volume means that the instructor has deep teaching skills. Even if an instructor with shallow skills is asked to organize the lecture time extensively, that won't work. I'm studying back-end, but I chose this course with the intention of improving my skills to an expert level, such as screen implementation.
