So I am just trying it the Ios simulator and made a quick ToDoList app using GPT to get a sense on how React Native works since I am trying to learn. I tried using this video

but when I run the command and look at the folder, I don’t see App.js anywhere. When I run the simulator it seems that i loads stuff from /app/(tabs)/ index.tsx and not App.js

Not sure what is happening and I was hoping understand why is that happening? is it some kind of new update?
