Make Custom Hook returns Object to not be confuse with useState which return an Array.
Create small component, if a component becomes too big: split it, add custom hooks or move the business logic to models. Even if you think your logic cannot be reused, it makes testing easier.
Use PropTypes on every component receiving props.
useState !== setState (be careful on updating Object state).
If your state management becomes complex, create a custom hook (check useModal, usePagination, useCard).
Start every handler by handle (and then the name of the action) to avoid confusion with onAction.
Give a verbose name to variables.
Extract business logic to file, example: toDetails function.
For HTML tag, one attribute per line if it contains more than 3 attributes.
