Từ DOM đến pixel, chinh phục hoàn toàn quá trình rendering của trình duyệt và CRP - [DOM 완전 정복 Part 3]

An Express.js journey from beginner to mastery, flowing like water! A backend journey where you learn properly by directly implementing from basic server concepts to completing a CRUD project.

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 course starts with a strategic AI Tic-Tac-Toe project and is a curriculum that completes the core concepts of object-oriented programming through practical examples. Through game implementation, you will train logic design and AI strategic thinking, and then directly experience OOP design techniques such as inheritance, composition, delegation, and encapsulation through code. This is recommended for those who want to go beyond syntax and grow into a 'designing developer' through a real project.

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 systematically masters intermediate to advanced CSS techniques such as "CSS Position, Transition, Transform, Animation, Flexbox, Grid, and Responsive Web Design," and equips you with skills immediately applicable in real-world projects through various hands-on practice projects.

Beyond simply using Express.js, this lecture will have you directly implementing its internal engine from scratch to finish, allowing you to truly internalize the operating principles of a real server. You will directly build all of Express's components, such as routers, middleware, request-response objects, static file handling, and template rendering, from the ground up, providing an experience that fosters growth as a server developer.

Through this course, students will broadly learn the basics and advanced concepts of JavaScript, from setting up the development environment to variables, conditional statements, functions, objects, and arrays. Through thorough review with practice exercises and quizzes, they will be able to develop problem-solving skills that can be immediately applied to web and mobile development practices.

The "Learning HTML + CSS Properly: Complete Mastery from Beginner to Practical Application Part 1" course is designed to provide a deep understanding of how the internet and the web work, and to solidify the basics of HTML/CSS through a practice-oriented curriculum. By taking this course, you can firmly grasp the essential concepts of web development and immediately apply them to projects.
