Bite-sized React.js: From Basics to Practice

I actually applied for the course before the renewal and completed it once, but after that, I stopped studying for about 1-2 years due to various circumstances, and then I came back because I felt the need to learn React again. When I came back, it was completely renewed this year! I remember that it was well-organized overall before, but the renewed version is easier to understand, and I feel like it has been supplemented in more detail. Usually, in cases of overall renewal like this, I only saw cases where it was opened as a new lecture, but I am grateful that existing students can continue to watch the renewed version. I can feel your sincerity towards the lecture and students, so I am moved by each episode. Only the final distribution stage is left, but I will watch the remaining 3 lectures well, review them diligently, and make them my own. Thank you so much.

I really wanted to finish the React course before the end of this year... I'm so happy to have achieved my personal goal!!! I strongly recommend this course to anyone who is still hesitating to buy it (I doubt there are any..?) I was a beginner who was interested in the front-end but didn't know what to do when I was about to graduate from college, so I quickly stopped the course because it was too difficult. Then, I realized that it would be a bit too much to take a React course without knowing JavaScript, so I took a Vanilla JavaScript course from my neighbor, Hyobin, bought a JS book separately, and took this course again with a basic understanding... I really had a great experience where I could understand everything so well!!!!! (Of course, it would be fine to just take Jeong-Hwan's class, but I wanted to dig deeper into the basics...) I wondered if the day would ever come when I would understand the code... But that day has come for me too... Of course, I'm still a super beginner, I've forgotten some of the content from the beginning of the course, and there are definitely parts that are difficult to code on my own, but by taking this React course, I got a feel for overall web development and I don't regret the time I spent taking this course. Above all, the clean visual materials + code + the diction that keeps you on your toes... You just have to buy this course. (Not an advertisement ;;) Jeong-Hwan, please keep teaching for a long time... Thank you! I'll go to the next TypeScript course now!!! Jeong-Hwan's class is one that you can trust and listen to.

I really enjoyed the class. It's the first time in my life that I've taken a tough online class. 😊😊 The biggest reason I was able to stick with it was because the quality of the lecture was so good. The instructor's diction is also very good, and above all, the lecture content is very rich. It's made up of really necessary content, and it's explained in a friendly way, so it was easy to follow and practice. After following the basic CRUD two sets (Todo, emotion diary), I felt that I had a good grasp of the concepts and that it would be of great help in the future in practical work. The after-service lecture on the React Router V7 version upgrade after the lecture was also good. If I encountered an error, I could search the community and find reference articles written by other people who had made mistakes like me, such as typos, which were helpful. I think that explaining things in such an easy and understandable way is a great quality for an instructor. Looking at the way you've created such a solid lecture, I think you must be a great developer as well~. Please make more lectures. I'm a backend developer, and I had some time left at the end of the year, so I decided to study React, and I'm proud of myself for choosing this lecture. 😊😊 I wish you the best of luck, instructor~ Stay healthy and please make good lectures in 2025 as well~.

I actually bought the lecture for a thousand won on April Fool's Day... just in case, like the lottery... But it really feels like I won the lottery. I feel bad that I'm able to listen to and study such a good lecture at almost no cost... The lecture is so kind, and the examples are explained so clearly that I really love it. Thank you so much, and I love you... 😭😭

It feels like eating meat wrapped in perilla leaves. The lecture content is delicious and not greasy~

I haven't watched them all yet, but from my perspective of having purchased several React lectures, this lecture is the best. Other lectures must have been created by experienced JavaScript developers. However, there is a problem. Experienced people give lectures while already having an image of how the code works in their heads. So, they give lectures while writing code like Uncle Bob. However, for beginners, it is frustrating to just follow the code without being able to visualize what is happening at all, and it is difficult to even grasp the concepts. In this lecture, before the code, the concept is explained by first visualizing what happens when a certain function is used, and then the code is shown, so I also get an image of the code working in my head while looking at the code. Most instructors are developers, not educators/education majors, so I feel that there are too many lectures being mass-produced without a standard for this effective teaching method, but this lecture is really the best. I have already purchased TypeScript before I have even watched the entire lecture. The quality is good, but the lecture fee is too much. I even bought the book so that I could have another cup of coffee. I don't often use the expression 'thank you' for lectures that I pay for with my own money, because it feels strange. Nevertheless, this lecture is 'very grateful'. If possible, I think it would be good if you also give lectures on Express.js, Next.js, and TDD!

I took React in English on a third-party site first. Since I was taking the course without a 100% understanding of English, I misunderstood the concepts or had problems with the explanations. So I looked for a React course on Inflearn and it looked good, so I took it. The course started from JavaScript again, so I was able to study JavaScript as well, which was great. I also learned a lot about React because it explained the concepts well. One thing that was disappointing was that when explaining A->C, there were a few parts where it would have been much easier to understand if the course had explained B in the middle, like A->B->C. Many other people also left questions about these in the Q&A section of the lecture. If only these parts could be improved, I think this would have been a perfect course.

This price is ridiculous for such an explanatory power and content. I think I could have paid double, but it's really a lecture like "The boss is crazy".. It's hard to say that I've digested it all yet, but I'll try to master it through repeated study. Thank you for making such a great lecture :) !!
