I hesitated to buy it because it was a bit old, but I'm lucky to be able to take such a high-quality course at this price! The only thing I regret is that it would have been nice if the parts that have changed in the latest React were written down briefly in the notes(?) that come out at the bottom of the lectures. ㅠㅠ The lectures also gave examples of how it can be used in practice, which helped me understand better. It's not boring, and time goes by quickly. However, when you're starting out with React, it would be better to take other basic courses and use React at least once before taking this course! I look forward to many more lectures in the future :)
