Introduction to React (Introduction to React)

React and Three.js all at once! From 3D basics to real-world projects and optimization tips!

Master React rendering principles and optimization to apply them in real-world situations and prepare for interviews!

This course is an introductory program designed for learners starting their React journey for the first time. It aims to help you systematically learn the basic syntax of JSX and develop practical skills through mini-projects where you can apply what you've learned. Beyond simple syntax learning, the curriculum is structured to help you understand the fundamental flow of React development and component-based development methods.

Learn to manage state effectively in React through hands-on projects and real-world applications. Master useState, useEffect, useReducer, Context API, and advanced state-management patterns while building interactive dashboards, e-commerce sites, and dynamic web apps. Gain practical skills to write clean, scalable React code that eliminates prop drilling and handles complex application state with confidence.

This is a practical course where you will directly create a timer app using React, Electron, and Zustand, and even deploy it to cross-platforms (Windows, macOS, Linux). Starting with familiar React web development, you can learn the entire flow of desktop app development, including global state management via Zustand and final GUI deployment!

If you're a React developer, you've probably wrestled with useMemo and useCallback at least once, wondering "Do I really have to do this manually?" Finally, the React Compiler has arrived to solve that dilemma. However, whenever new technology emerges, reading through extensive official documentation from start to finish can be overwhelming. That's why I've carefully analyzed the React Compiler official documentation and prepared a course that extracts only the essentials for easy understanding. This course covers: - Why: Why the React Compiler was created and how it differs from existing approaches - How: Installation and configuration methods to apply directly to your projects - Troubleshooting: Key precautions emphasized in the official documentation and error resolution tips Now break free from the pain of manual memoization and focus solely on business logic. This course will upgrade your React development experience to the next level.

In this course, you will be able to create a Reddit website from scratch, step by step.

Solidify your foundation in Python/Django web service development. Learning Django takes time, but you can maximize your productivity through iterative development. Turn your imagination into reality.

This course teaches you how to build a web application using React and Firebase, implementing core features used in real-world services such as login, post management, file uploading, and profile management. You will build a complete web service step-by-step, implementing email and social login via Firebase Authentication, Firestore-based data storage and real-time data processing, file uploading using Firebase Storage, and profile management features. This course is designed for frontend developers to understand how to quickly implement web services using Firebase without the need for complex server construction.

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

"A hands-on web development project course that covers everything from planning and design to implementation and deployment using Generative AI." We will complete the entire process together step-by-step—starting from idea conception, quickly creating designs with AI, implementing a functional website with React, and finally deploying it to the internet. Latest AI tools like Stitch and Figma Make will assist with your design work, and even complex coding will be taught in a way that is easy to follow step-by-step.

The goal is to acquire basic knowledge of React Native for mobile app front-end development. This course is designed to enable non-experts to easily develop native mobile apps by utilizing languages/APIs with low entry barriers.

This is mission content for a development project. We provide a PRD planning document, Figma designs, and API endpoints so that you can practice by implementing a timer app called DevTime yourself. Make the knowledge you have learned completely your own by implementing a project at a level similar to an actual service 🚀
