Why we still use React HOCs

The text discusses the challenges and solutions in managing loading states in React applications, focusing on the limitations of directly using hooks like `useAuthInfo` that include a loading state. It critiques the repetitive nature of handling loading states in client-side React applications and proposes using Higher Order Components (HOCs) as a solution to reduce boilerplate code and simplify component logic. The text illustrates how HOCs, such as `withHookWithLoadingState`, can encapsulate loading state logic and automatically pass necessary data to components, thus streamlining the development process. It also mentions specific HOCs like `withAuthInfo` and `withRequiredAuthInfo`, which simplify authentication checks by skipping unnecessary state handling when user information is already known. While acknowledging the complexities in implementing HOCs, such as ensuring correct type definitions and handling static methods and refs, the text argues that HOCs can offer a cleaner codebase, particularly in scenarios where hooks are frequently used or when maintaining a library.
