No matter how much you study React, Next.js, or Vue, if the code feels abstract and the structure isn't clearly understood, the root cause might be a lack of understanding of DOM. DOM is the foundation of all frontend frameworks and the entity that connects the structure and behavior of web pages. This lecture goes beyond simple selectors or manipulation methods, teaching step-by-step from the very beginning how HTML transforms into DOM objects and how to select, traverse, and manipulate this structure. It is the Part 1 introductory lecture of 'Complete DOM Mastery'. HTML tags are just structure, and JavaScript is just behavior, but DOM is the core that connects the two. If you clearly understand this connection, you'll be able to precisely grasp the true structure and flow within any framework you use.

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.

This is not just a lecture you listen to and forget. This course aims not for "the moment you understand React" but for "the moment you can actually handle React." In every section, you'll complete missions alongside the lectures, solve practice problems directly, and learn by implementing core concepts like JSX, Virtual DOM, State, and useEffect with your own hands. When you complete the course, you won't just be a beginner who knows React syntax, but a developer who can explain and utilize everything from component design to rendering flow on your own. "Not just a class you listen to, but learning you build to completion." Understand the essence of React and experience the world of declarative UI firsthand.
