I don't use it at work.. I decided to take the course because I was curious and interested in Node, React, Docker, and AWS deployment. The course materials are well organized, and each lecture is not too long, so it was easy to implement following the lecture, and the explanations were good. However, what's a bit disappointing is that I got lost in the deployment part and barely managed to deploy it. ㅋ Deploying to Docker and AWS.. These two are the parts I'm most unfamiliar with, so I wanted to experience them the most through the course. In the beginning, the screen implementation was explained in detail, but the course materials and videos were very disappointing in the deployment part. Overall, I think it's a good course to grasp the basic concepts and implement them!
