It was really good because it contained all the parts I needed to get started! When I first started coding, I took the Life Coding Web Application Creation class, and I studied by just following along and memorizing a little bit, but as I studied JavaScript, libraries, and frameworks, I got confused about the concepts, so I looked them up again, and it was good because I had all the concepts I needed! At first, I only knew that getElementById and addEventLinster were used to control events, but I also learned about the querySelector method, which is similar to jQuery, and it was good that I could naturally look at selectors again! I am satisfied that I can gain something by going through the lectures, which are easy if they are easy and difficult if they are difficult, and I will start studying again! I think it will be a great help to look them up whenever I get confused!!
