problems

• naming classes in css
• dividing the react components into smaller chunks, like which would make the code more reusable

unsure areas

questions

• how can I make use of useMemo and useCallback for making fetch reqeusts?
• what are the best practices for optimizing the search component (it is in the CountryList.jsx file)?
• how to break down components and make code DRY?

GENERAL QUESTION How do you start your project - like do you first start writing the logic and add design or do you study the design first and make classes and then add logic?
