This lecture is for those who want to learn everything from the basics of JavaScript to various applied technologies used in the field, including portfolios, in one lecture, rather than looking for separate lectures on basic JavaScript, applied JavaScript, and portfolios.

This course will teach you JavaScript through theory and practice. This course is for those who are somewhat familiar with JavaScript. Part 1 covers JavaScript classes and object-oriented programming.

This is the most solid foundation course for beginners who want to learn JavaScript properly. This course will be the starting point for understanding the language called JavaScript, and you can perfectly prepare the basics to become a front-end (Vue, React, Angular) developer and server (Node.js) developer.

This is a project-oriented course where you will build a "ToDo List" app using React and TypeScript with a professional touch. Beyond simply learning syntax, you will gain practical experience in using TypeScript by completing a real-world service—from component structure design and state management to type application, feature implementation, local storage integration, and deployment.

Cultivate advanced programming language utilization skills and software design and implementation skills combining functional, object-oriented, and LISP paradigms, necessary for growing into a mid-to-senior level developer.

This is an introductory course where you will learn the core syntax of TypeScript to improve type safety and code readability through hands-on practice. You will learn everything from project environment setup to interfaces, generics, and utility types using real-world code examples.

This is an introductory course to the front end using Next.js and Tailwind CSS. It is designed to complete static deployment without a backend, so even beginners can experience the satisfaction of completion.

"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.

jQuery, the JavaScript library used by over 75% of websites worldwide! This course is designed to help you build a solid foundation by understanding the principles rather than just flashy effects. Learn everything from jQuery basics to advanced applications to complete your own portfolio or apply it directly in the field.

This course is for those who are preparing for a coding test using JavaScript. It is designed to teach step-by-step, from fun basic problems to advanced algorithms.

mongoDB, NoSQL You hear a lot these days, but is it still an unfamiliar database? Aren't you using it like a relational database (RDS/SQL)? No matter how good the technology is, if it's not used correctly, it will have the opposite effect. That's why we often see cases of failure in using MongoDB. This lecture will teach you everything from basic concepts to practical know-how so that you can use MongoDB as MongoDB-like as possible.
