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.

Did you give up while studying React? Even complete beginners new to coding and non-majors can find their way to React without giving up, from JavaScript all the way to React.

Asynchronous programming is a core concept in JavaScript. This course will help you fully understand and use asynchronous programming.

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.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!

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.

Develop your ability to find the core of a problem and solve it with the 'Top 10 JavaScript Algorithms' that cover the most frequently asked types of problems!

JavaScript, TypeScript Next is backend development! You will be able to develop REST API backends using NestJS, develop and deploy Socket IO.

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 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.

Through this lecture, students can create a web service similar to Instagram using HTML, CSS, and JS. (Only the front-end is implemented! The back-end server construction will be filmed in a later lecture.)

"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 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.
