Thank you so much for letting me know about the latest version of Rails. Basically, explaining through the official guide and teaching me step by step was extremely helpful. Through the course, I learned about Rails' characteristics and advantages, and I was able to apply them usefully in practical work. The way you utilized AI was also very useful, and it was great that you filmed new lectures differently from when I was actively taking the course. I came to realize how productive and attractive RoR is as a framework. In the future, it would be great if you could film lectures on topics related to deeper or useful features of the Ruby language, features that are usefully used in RoR like Sidekiq, or advanced versions of RoR. In Korea where Spring is the majority, having Rails lectures on Inflearn felt so grateful and like a sweet rain. Thank you for filming such a good course.
