This is a hands-on project course that adds interactive features with JavaScript to a beautifully completed cafe homepage built with HTML and CSS. You can naturally learn all the JavaScript fundamentals by following the story of Minji and Teacher Code, from button clicks, menu filtering, reservation forms, and dark mode toggle to API integration. With 5 hours of learning, even beginners can create dynamic web applications.

Let's develop an SPA with Vanilla JavaScript while learning everything from basic syntax to advanced concepts🔥

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.

We introduce the main concepts, grammar, and utilization methods of JavaScript, the programming language that runs websites. This is an introductory JavaScript course that even those who are just starting out with HTML/CSS can easily understand.

🚀 This is a mini-project practical lecture suitable for those who have just finished studying JavaScript grammar. It will help you break through the gap between basic JavaScript grammar and frameworks such as React or Vue. ✨

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.

"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.

This course is a practical, hands-on guide for those who want to learn how to maximize development productivity in the AI era. Beyond simply learning how to use AI, we focus on how to utilize Claude Code in a real-world development environment and how to produce "proper results." Many developers use AI but still face issues such as: ❌ Inconsistent results ❌ Poor code quality ❌ Increasing project complexity To solve these problems, this course teaches you how to utilize AI as a "development partner" rather than just a tool through: ✔ Spec-based workflows ✔ Structured command systems ✔ Sub-agent and automation strategies Furthermore, you will gain the experience of completing and deploying a full application from start to finish by integrating with real-world services such as Firebase, Figma, GitHub, and Vercel.

In this course, we will practice developing programming thinking skills using JavaScript. Starting with a multiplication table web game, we will build various projects together, including Word Chain, Number Baseball, Response Rate Test, Tic-Tac-Toe, Lotto Generator, Rock-Paper-Scissors, Card Matching Game, Text RPG, Minesweeper, 2048, and Whack-a-Mole.

Complete everything from design to TDD and CI with Claude Code. Taking a single feature from one line of spec all the way to main merge.

It covers machine learning concepts within the JavaScript environment. It covers the patterns and code for implementing machine learning with JavaScript and TensorFlow.js.

The days of feeling relieved by black-box code spat out by AI are over. By piercing through the physical limitations of computers and the inner workings of the Node.js core engine, we provide you with the engineering control to remain unshakable in the face of any traffic surge.

Feeling overwhelmed by where to start with complex data analysis? I will clearly guide you through how to utilize R and AI Tutors using the practical know-how I've built up.

This course goes beyond just using Express.js—you'll implement its internal engine from scratch to truly understand how real servers work. You'll gain hands-on experience growing as a server developer by building all of Express's components from the ground up, including routers, middleware, request-response objects, static file handling, and template rendering.

We will develop an avatar-based community app using React Native. You will learn the process of creating a high-quality community app that includes not only post creation but also comments/replies, likes, polls, and avatar generation.

We will write server code using the JavaScript-based web framework Express.js to understand basic usage and server operation principles. We will also study that frontend essentially requires a server, and enhance our understanding by learning about the processes behind various techniques such as static serving and dynamic rendering.

This is a full-stack restaurant map tutorial that allows you to learn everything from front-end, back-end, Kakao Map API usage, and deployment all at once while creating a restaurant map of your favorite YouTuber.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

Supabase to give wings to full-stack development! Complete full-stack development in 2 hours with Supabase, a superset of Firebase.
