I was hired as a new employee and had to study RN in a hurry, so I logged into Inflearn and there was a notification for John's new lecture opening, so I hurriedly purchased it. I studied John's React before and got a job, and I'm getting help from John this time too. There aren't many up-to-date React Native lectures on Inflearn or other sites, and they don't explain in such detail. If you're in a similar situation to me, I highly recommend this lecture. It's definitely not worth 30,000 won. These days, everyone just pastes and pastes snippets, but John writes from beginning to end. And if you don't know Redux, no one makes a separate lecture. Ha, as expected, it's the best. The flow of the lecture was so good that I bought it in the morning and have been listening to it continuously until now. As expected, John's lectures that I trust and buy are the best.
Disappointing points
1. There are many parts where errors are fixed later
-> If you are someone who frequently presses save and checks the screen, you may spend a lot of time troubleshooting errors, wondering 'Why isn't it working?', but you should be careful and take the course because the parts that are fixed later are shown in the video.
Good points
1. Before each video starts, they clearly explain 'This is how it will be implemented' and start, so you can understand the design and functions in your head while following the code.
2. They prepare countermeasures for various errors in advance, and they are meticulous and kind enough to not copy and paste even easy codes but to do it one by one.
3. Considering the price of the course, it is the best course composition.
Review
I took this course after learning Java and having basic coding skills and not knowing React, and then I took Nomad Coder's ReactNative beginner course. If I had to compare, the course composition was really good. I felt like I learned everything I needed to implement to some extent. It took me a while to listen to the end because it was my first time with React, but if I had basic React and CSS, I think I could have understood it quickly just by listening to the part about creating an Instagram app. Thank you for the great lecture.
I really appreciate that you display the completed code and example images for each new component in every class, explaining what each part does. Anyone with even a little knowledge of React will probably be able to follow along. It might be a matter of preference, but I found it helpful when you corrected typos or other mistakes that prevented the screen from mounting. (And that time is very short.)
Also, I sincerely appreciated that you calmly explained potentially confusing parts again during the class. Sometimes, with other online courses, I don't understand but feel awkward asking questions, so I just follow along and then give up. In that regard, I felt the explanations were very kind.
However, a minor point is that as we got to the later parts, it felt like we were focusing only on UI implementation rather than learning new features. For example, the "like" or "follow" buttons only used useState, and it felt like they were just screen configurations rather than having a connected feel between the pages, which was a bit disappointing. Still, I think I can now take other courses or explore further on my own based on this class.
If a beginner-intermediate or intermediate-level class is organized after this one, I would definitely take it.
