Summary

In this chapter, we learned about view patterns that will be very useful later on in this book. Now we know how to write concise JSX and type check components. We can also compose common built-in components from the React Native library. When we need to, we can write the markup of a simple form and know how to handle the input. We compared controlled and uncontrolled inputs and dove deep into how TextInput works. If some errors occur, our error boundaries will handle the problem.

Finally, we made sure that we have a strict style guide on how to write React Native code, and we enforced these rules by using ESLint.

In the next chapter, we will work on styling the components we have learned. Thanks to this, our application will look nice and professional.
