The best roadmap for moving beyond React basics to the next level! True to its title, this course goes beyond simple feature implementation to help you become a "truly skilled developer." When I was self-studying, concepts like State and Props were swirling around in my head without being fully understood, which was frustrating. However, thanks to the instructor's clear diction and intuitive visual aids, those scattered concepts finally clicked into place. In particular, the process of first building a solid theoretical foundation and then coding along while watching the instructor's detailed explanations of the example source code was incredibly beneficial. Since the structure focuses on hands-on experience rather than just watching, I could actually feel my skills improving. This course serves as a clear guideline for those who have finished the basics of React but are experiencing a plateau in moving to the next stage. Thank you so much for creating such a great course!

Teacher Nak-ja's React course that I've been waiting for is finally out!!! I first learned about Teacher Nak-ja through the book <Must Have Seong Nak-hyeon's JSP Java Web Programming>, and his kind explanations and examples from a beginner's perspective were a huge help in mastering that technology. I recently happened to find out that he published a React book. While the book itself is perfect for getting started, I searched for this course because I wanted to hear his lectures as well. If I were to pick out the characteristics of Teacher Nak-ja's lectures: 1. They are great for beginners to follow step-by-step. When learning a new technology, there are always many unfamiliar concepts since it's the first time, and I often got stuck on everything from installation to writing code. However, Teacher Nak-ja's lectures are great because he explains everything kindly and in detail, making it feel like he is coding right alongside the student. Even if the lecture time doesn't seem short on paper, it doesn't feel long because it saves so much time that would otherwise be spent struggling when stuck. 2. It's great that he mentions the learning order and overview at the start. When listening to other instructors, they often give a very brief explanation of what will be covered and jump straight into the main subject. Teacher Nak-ja mentions a learning overview, which makes it clear exactly what I will be learning in today's lecture. If I don't have a big-picture understanding of what I'm studying, I quickly forget what I learned even after finishing the lecture. But here, a kind of magic happens where I can visualize today's content just by recalling the learning overview and sequence. Haha. It was also great for review, as I could remind myself of the key points by looking at the overview again after finishing the lecture. 3. Not only are there abundant examples, but he never loses sight of the core of React throughout the course. I liked that the course organizes the core theories you need to know at the beginning and allows you to apply those theories immediately through plenty of practical examples. If you don't know the theory, you won't understand the core principles or be able to apply them no matter how many examples there are. This is a well-balanced course that misses neither theory nor practice. What I found fascinating is that when content is abundant, a lecture can easily lose focus and become distracting, but perhaps because of his long teaching experience, the immersion was incredible, allowing me to stay focused on the core throughout the entire lecture. 4. His voice is so good. This is just my personal preference. Hahaha. I know you must be busy, Teacher, so thank you for producing such a great course in addition to the book. I look forward to the next one! ^^/
