Higher-Order Components — Reusing Behavior Without Inheritance

When two components need the same loading logic, collapse behavior, or data-fetching pattern, the wrong instinct is inheritance. After this lesson you can build a Higher-Order Component that injects shared behavior into any wrapped component, explain why HOCs are preferred over class inheritance for code reuse in React, and identify the prop-forwarding pattern that prevents HOCs from silently swallowing props.
