This is a project-centered course that builds a "To-Do List Management App" with practical skills using React + TypeScript. Rather than just learning syntax, you can develop a sense for TypeScript application by completing it as an actual service through component structure design → state management → type application → feature implementation → local storage integration → deployment.

This is an introductory course that focuses on learning TypeScript's core syntax through hands-on practice to improve type safety and code readability. You'll learn through real code examples, from project environment setup to interfaces, generics, and utility types.

TypeScript syntax that front-end beginners must learn! We thoroughly explore the TypeScript language, from basic to advanced!

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 systematically covers the core technologies of front-end development, focusing on HTML5, CSS3, and JavaScript as the foundation of web development.

The Ultimate JavaScript Course! It covers execution context structures and mechanisms based on ES2025, the Event Loop, and multi-threading. It also explores the language culture embedded within JavaScript.

The ES6+ Understanding Course provides an in-depth introduction to the ES6 and subsequent standard ECMAScript specifications for JavaScript, with a theoretical foundation, and explains the differences from ES5, as well as the concepts and operating principles.

"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.

Most sites are created with a combination of designers + publishers + developers. If you use Sencha's ExtJS components purely, you can develop screens without designers and publishers. However, if you use ExtJS for commercial purposes, please be sure to understand the license policy and use it.

Apps play an important role in our daily lives. However, the process of developing and maintaining native apps is long and complex, and can be quite costly. This course introduces Progressive Web Apps (PWA), an alternative that has been gaining attention as of September 2024. PWA combines the advantages of web technology and native apps, enabling faster and more efficient app development and maintenance. Through hands-on practice, you'll learn the concepts, advantages, and implementation methods of PWA step by step, and develop the skills to apply them directly in real-world scenarios.

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.

We deal with ideas. You can logically organize the core and fundamentals of JavaScript. You can structure your own JavaScript experiences and thoughts. You can establish the technical logic of JavaScript. You can broaden your perspective to see the entirety of JavaScript. You can prepare for JavaScript technical interview questions.
