This course covers the Critical Rendering Path (CRP) process from start to finish, where the browser receives HTML to create the DOM, combines it with the CSSOM, and renders pixels on the screen. Beyond simple DOM manipulation, you'll learn how CSS and JS impact performance, image and font optimization, Lazy Loading, Intersection Observer, virtual lists, and DevTools practice, gaining practical strategies to noticeably improve real web performance.

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.
