I have now taken 70% of the entire course, and I still trust Instructor Jang Ki-hyo's lectures!!! I learned Vue.js from Instructor Jang Ki-hyo, and now I am learning TypeScript as well.. Since I don't have a mentor at my workplace, I feel like Instructor Jang Ki-hyo has become my mentor; I understood really quickly because he explained the basics of TypeScript in detail! At first, I was scared of the generic part of TypeScript, but since it felt difficult, the instructor explained it in more detail and concretely in several lectures, so I am listening to the lecture with peace of mind. Thanks to the quizzes given in between, I was able to determine where I didn't understand, which was really good ㅎㅎ The Vue.js project I am currently working on at my company is made up entirely of JavaScript, but after I finish this lecture and practice enough, I plan to migrate everything to TypeScript! I am really learning a lot ㅠㅠ.. Thank you so much, Instructor Jang Ki-hyo!!
