‘Where and how should I store files that look like images? Should I store them in a database? Or on a server hard drive? How can I reduce server load? How can I quickly load many images without stuttering? AWS S3? CDN?! I just want to store and load images, so why are there so many elements? What role do each of these elements play, and how should they be combined?’ I will teach you all the necessary elements related to image files, from start to finish, as a full stack :)

New to React? You need to think about how to learn React's fundamental concepts solidly yet quickly. Start with Next.js and JavaScript with minimal knowledge. Let's develop by selecting only the essential examples needed for real-world development. The Todo example is so important that you should develop it twice. Once focusing on components, and then focusing on routing that handles browser paths! Use Zustand for login! You can handle global state with a really small amount of code.

This course goes beyond simple DOM manipulation, deeply learning how to dynamically compose and react to web UIs within interactions with actual users. It's structured for you to learn by directly implementing common issues encountered in practice, from the essence of event systems, bubbling and capturing, event delegation, real-time UX feedback, to performance optimization using throttle & debounce. Based on an understanding of the DOM tree structure, you will develop the ability to flexibly connect event flow and state changes.
