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.

"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.
