Higher Order Components
Higher Order Components (HOCs) are an advanced pattern in React for reusing component logic. They are functions that take a component and return a new component with enhanced or modified behavior, such as adding props, state, or lifecycle methods. This pattern promotes code reuse and separation of concerns by abstracting common functionality away from individual components.
Developers should learn HOCs when building large-scale React applications to avoid code duplication and manage cross-cutting concerns like authentication, logging, or data fetching. They are particularly useful in scenarios where multiple components need shared logic, such as handling user permissions or integrating with external APIs, allowing for cleaner and more maintainable codebases.
