This lecture is the real deal. Usually, front-end beginners (newbies) don't have much understanding of the development environment itself (including me). After watching this lecture, I thought, "Oh, this is it," "This is how it was, so I should look at this next time," "If I want to do it, I should modify this," etc. It is very helpful for building basic and overall flow and knowledge about the front-end development environment. Although you already share information for free on your blog, it is much better to acquire knowledge through this lecture. (For reference, I am taking Captain Pangyo's lecture for the fourth time. ==> I emphasize this as the opinion of a real student.)
