This was a course where I could learn everything from the basics to fundamentals of HTML, CSS, and Javascript. In addition to the lectures, various contents such as coding tests and practical training were utilized, allowing me to learn and reinforce the knowledge I learned in the lectures several times. For example, in the case of the coding test of the company's own platform, reference code was provided so I could receive feedback on my code, and in the case of the practical project, I could review and utilize the contents I had learned so far. In addition, it was also good that the management team continuously managed the learning in addition to the learning content, which helped me to faithfully complete the course. Among them, the part that I liked the most was that when I had a question about a difficult part during the learning, the training engineers answered almost in real time. Although I learned mostly online, the management and feedback made me feel like I was learning offline, and I was able to complete the course well. I think that even people who have not yet encountered front-end can sufficiently acquire the basics of related languages in a short period of time through this course.
