Storybooks and UI tests that can be applied directly to practice

Artificial Intelligence, AI, agents... They might seem grand, but once you try them, they're not as difficult as you think. That's why it's important to implement simple features yourself. Through practical projects that can actually be used at a company, you'll directly experience various use cases and learn how to utilize and apply AI agents.

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.
