Complete JavaScript in One Go: From Vanilla JavaScript to SPA Development

I had already taken JavaScript courses once or twice before. But strangely, I always felt like I knew it, but when I actually tried to use it, it never worked out well. This course felt like it organized all those ambiguous parts one by one. It wasn't just about explaining syntax and ending there, but it was great that the instructor continuously connected and explained why this concept is needed and how it's used later in SPAs. What I especially liked was the project section. Usually, you just follow along and that's it, but this course had a flow of intermediate project → recognizing problems → supplementing concepts → final project, so I couldn't help but think. Honestly, it wasn't easy, but I gained a lot from it. The course materials (handbook) are also well-organized, so I keep referring to them not only when taking the course but also when reviewing. I would recommend this course to anyone who wants to properly organize JavaScript once again.

I completed the course! What I felt while completing the course was that I was happy to be able to take a really meticulously prepared lecture at a reasonable price. Development courses have wildly varying prices, and I'm currently taking several courses together, but just because the price is expensive doesn't mean the instructor properly answers questions or provides code updates. So I was quite disappointed with a certain instructor, but listening to Hyobin's lecture, it's really clearly different. It's a bit awkward to compare with others, but I hope educators like Hyobin become even more successful. It would be so great if you expanded your courses to React or Next.js beyond JavaScript! As an Inflearn user for n years, this was the most cost-effective and beneficial course. Of course, the final project was difficult, but I think the difficulty was meant to humbly encourage us to review again, which was motivating. I've never left such a long course review, but I became a fan of Hyobin and am leaving this review to recommend it to others! The detailed handbook, clear diction, clean examples, quick Q&A responses - there wasn't a single disappointing aspect. I hope you become even more famous on Inflearn and in the education industry! Thank you for the great course!

I've been preparing for a job change and am returning to FE after almost 5 years. I was overwhelmed about where to start studying again, Through this course, I was able to learn so much - from reviewing parts I knew lightly before, to new grammar structures, and even advanced topics like objects/properties/components at the unit level. The project work was especially beneficial. Rather than just learning basic knowledge & grammar, I learned about how to use it effectively in actual work, and it was even more interesting because we worked on a new project instead of the usual todo list! I'm really looking forward to the next course! Thank you for the great lecture :)

Just one last word: this is truly the ultimate vanilla JavaScript course. 1. Your pronunciation is excellent, so everything comes through clearly. 2. The course covers both theory and practical application. I wrote a long review earlier, but my computer suddenly crashed and I had to reboot, so I'm writing it again. While finishing the course, I felt inexplicably emotional. Finally, I will take any other courses Hyobin creates, including React and Next.js. I don't know about others, but for me, this was a truly educational and helpful, the best course. Thank you for your hard work, and thank you, instructor! 😭😭😭😭😭😭😭😭😭

The visuals are neat and, above all, I liked that you taught me step by step slowly through live coding. I will continue to take the class and complete it! Thank you for the great lecture.

I found out about this lecture by joining the Han-ib community after watching Lee Jung-hwan's lecture. I've only used SPAs before, but I've never built one myself, so I was already clicking the payment button 😆😆. I couldn't participate in the Han-ib challenge because I'm already working on something else, but I'm very satisfied with the lecture. I skipped through the parts I already knew and only listened to the latter half of the lecture while reviewing with the handbook, but I'm very satisfied with the lecture. Lee Jung-hwan was easy to listen to because of his good diction, but Hyobin also has exceptionally good diction. Thank you.

The voice is clear and the pronunciation is clear and precise, so it's easy to listen to even at double speed! And it's easy to understand. Thank you.

Even if you are new to JavaScript, I think this is the best lecture to study from the basics before learning React! Thank you for making such a great lecture!!
