React Native App Screen - Code Quality












0












$begingroup$


I've been building a two-sided (both clients and service providers would use the app) appointment booking app. This is a screen from which a service provider can confirm their profile after having completed the fields across multiple screens previously.



I have a couple of React/React Native specific questions:




  • Is it okay to have components defined within parent components that access the parent component's props directly?

  • Is it okay to have onPress handlers defined directly in the JSX directly?


I would also appreciate any and all general feedback. Tear it up! Thanks.
