Take the leap from a beginner to an intermediate developer by learning Qt/QML programming skills and the latest technologies through real-world projects.

This course is a course to learn the basics of Python Windows programming. It enhances understanding by explaining how to use widgets and providing sample codes.

In this course, you will learn React from basic to intermediate level. This single course is designed to help you learn the concepts, practice them, and acquire most of the knowledge you need for React all at once.

This course goes beyond the React beginner level and is an intermediate learning course that intensively covers the principles and usage of Hooks, which are most frequently utilized in practical development. Through Hooks, the core tool of functional components, you can learn step-by-step how to implement state management, lifecycle control, performance optimization, and more. In particular, it systematically organizes the roles and usage patterns of basic Hooks like useState and useEffect, as well as advanced Hooks such as useRef, useMemo, and useCallback, and is structured to help you understand which Hook to choose for different situations. Through practical examples, you'll go beyond simple code writing to experience: State management optimization between components Prevention of unnecessary rendering Dynamic data management and DOM control This allows you to develop the intuition to solve problems frequently encountered in real projects. Upon completing this course, you'll master Hook-based development flow, which is the core of React, and be able to confidently apply it to more complex application structures.

This course will help you develop mobile apps that can be serviced on Android and iOS using web development.

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.

Learn about MAUI cross-platform development, which lets you develop and run Windows, macOS, iOS, and Android applications with a single code base.
