More FAQs in What Are Higher-Order Components in React and How Do They Work?
A Higher-Order Component is a function that takes a component and returns a new component. The new component wraps the original and adds extra behavior, like data fetching or auth checks, and passes props to the wrapped component.
Before hooks, there was no clean way to reuse stateful logic across components. HOCs let you share that logic by wrapping components, so multiple components could reuse the same behavior.
Prop name collisions between wrapped props, deep nesting that is hard to read, difficulty typing, and harder debugging because of wrapper layers. These issues led to hooks replacing them.
