I was working as an embedded developer and wanted to switch to front-end, so I wanted to learn the overall flow of front-end development, so I looked for a lecture and ended up taking the course. I took the course knowing the basics of React. While listening to the lecture, I followed along, but when I had trouble or did not understand the concept, I looked up the official documentation and the internet to solve and understand it, so I got used to writing code, and it was good that I could study not only React but also Next.js and Typescript. I had never used Firebase before, but I was glad to use it, and it was also good that you introduced me to other useful libraries. I think I will be able to create my own app in the future based on what I learned. Thank you for making such a useful lecture.
