Just because it's taught easily doesn't mean it's taught shallowly, so don't hesitate and buy when the price is low. For beginners or those who have studied but can't find direction, I think you can just invest boldly. While working on a graduation project with Spring boot, what appeared on screen was too absurd, so I started listening (to the lecture), and since the screen looks good and I get immediate visual results, it's really fun!! I listened intensely during the holiday, so much so that I want to take the nest lecture too, out of ambition. I am very satisfied with the quality of the lecture. ((And in the past, when I took other lectures, even when told to read official documents, I didn't read them much because there was too much and it was bothersome, but here, they put all the helpful reference links below, so you can really feel how much effort was put in. 😊..😊))
