I really enjoyed learning JavaScript by studying and analyzing it using the browser console. I only knew a little bit about JS and used React and Node, but while taking this lecture, I realized a lot of things like, "Oh, this is how it works." Thanks to Yalko's easy explanations, I was able to learn advanced concepts easily. I think this will be a really fun lecture for those who want to study JS properly, as the title suggests. I especially recommend it to those who use JS in the field.
