I am a developer who got into RN through Zerocho's delivery app clone coding course and is currently developing apps with RN and Expo in the field. If the previous RN course was cli-based, this course actively utilizes Expo, a framework that plays the role of Next.js in RN. The previous delivery app clone course also contained all the essential parts for RN development, but this course was great because it explained all the changes due to Expo updates in detail. While other courses felt like just scratching the surface of RN using Expo Go, Zerocho's course used development build and even native libraries to teach all the RN and Expo knowledge needed in professional work. Even though I was already using Expo, he clearly explained the parts I was ambiguous about. As a bonus, it was nice to see Zerocho using Cursor. Expo is a very convenient and good framework, but it feels difficult to adopt due to its barrier to entry. I hope this course serves as an opportunity to spread the awareness that it's good to start new projects with Expo.
