This lecture has been around for quite some time, but I'm just now leaving a review. Since I just followed the code without any detailed explanations on the backend, I didn't understand it, so I bought a book and studied on the internet, and at some point I forgot about this lecture. In the end, I was able to create a server with Django REST Framework and implement a simple crud function with React for the front end, but looking back now, this lecture's explanations are really lacking. Those who want to take this lecture should study separately like me to understand the lecture's contents. Originally, a lecture can't teach you everything, and in the end, you have to find out on your own, but that's why I think it's worth buying this lecture for 110,000 won.
