Hello, I am leaving a review after signing up for the course and binge-watching for 5 hours and 30 minutes (I've watched about 10% of the total curriculum). My coding level before taking the course: - Started with "vibe coding" a year and a half ago. It was fun at first, but I felt frustrated by the roadblocks caused by my lack of development knowledge, so I studied the flow of HTML, CSS, and JS through YouTube. - From that point on, I collaborated well with AI, and the process of completing programs or websites at the level I wanted was enjoyable. I started earning a small amount of pocket money, and now I earn as much from my coding side hustle as I do from my main job. - My annual income has essentially doubled, but with the release of the Claude Opus model, I began to feel strongly that as a non-major, the AI's capabilities have become so incredibly high that I kept thinking, 'I feel like I could be doing this more efficiently...' Because I lacked development knowledge, it was impossible to maximize the AI's potential, and I hit a major wall. - 'Do this for me' -> 'It's not working, there's this error, do it again' -> 'Now there's this error'... After over a year of infinitely repeating this cycle of relying solely on AI until it worked without even knowing the cause, I got exhausted. I felt deeply that this was inefficient in an era where we must utilize AI agents, so I sought out this course to grow. The process of choosing this course: - I was tired of the cliché AI agent introduction videos flooding YouTube every day. - I was fed up with content creators who have zero services of their own but try to win people over with titles like 'X years of experience at such-and-such company.' - I was disappointed by thumbnails and content that took knowledge you could find just by asking AI, turned it into a script via AI, and packaged it as if it were something amazing. - Those who have achieved even small results through "vibe coding" like me will know: for developer creators, a single service they built themselves proves their skills better than a hundred words. Looking at this instructor's services and YouTube content, I was confident that if I could absorb even a fraction of what's in this course, I would be able to grow significantly. Course Review: - Rather than explaining every single developmental concept, the instructor shares direct hands-on experience from the field, which makes it distinctly different and engaging. It's not a one-way explanation that ChatGPT could provide, but a sharing of experiences that keeps me focused and curious about what comes next. - There are so many practical techniques that even AI doesn't tell you. I feel like, 'Everything I've been doing until now was just a struggle in the dark...' There are so many methods shown in this course that I have never seen once on YouTube. I almost feel like I want to keep this to myself. - It's great to see how an elite senior developer actually works; it gives me a clear understanding of how to set up my AI partner and how to equip and move forward with these skills for a lifetime. - For us "vibe coders," the goal isn't necessarily to get a job at a company, so we don't need to memorize development knowledge well enough to explain it. Instead, we focus on how to configure/build AI and efficiently achieve the final goal. I highly recommend this to my fellow vibe coders who want to achieve that. I feel like I've gained my freedom. haha

I planned to complete the entire course during the holiday, but there's really a lot of content. It's literally like a comprehensive gift set that lets you see the entire frontend at a glance. I could grasp the overall flow, and the core and important content was explained through practical examples, so I was able to listen with such immersion that I thought "I need to try this at work right after the holiday ends." Having some backend experience helped me understand it better. The course materials were well-prepared, which was great even for the difficult parts. And overall, the conceptual explanations were provided together, so I felt it was a good course suitable for the AI era. After taking this course, I can see shortcomings that weren't visible before, and I also think about how this could be improved. The goal of this course is to have different eyes when looking at code compared to before, and I really became able to think about many things even when looking at a single piece of code. Thank you for the great course.

I've only made it through about 1 chapter so far, so this isn't a comprehensive review, but it was good. There's a book called JavaScript Deep Dive that has a similar feel. That book also tends to be polarizing - it gets poor reviews from people who prefer project-based hands-on learning, and this course is similarly focused on theory and key examples.
