How does children work, and why is it fundamental to composition?
Tests React composition knowledge. Good answer: children is a prop holding nested JSX; a Card wrapper renders {children} to let parents inject markup; contrast with prop-driven text. Red flag: calling children magic syntax instead of a standard prop.
Tests whether you prefer React composition over configuration. A strong answer explains that children is simply a prop containing nested JSX, demonstrates a reusable wrapper like Card or Modal that renders {children} to delegate content responsibility upward, and highlights why composition beats prop-driven content injection for flexibility. Red flag: treating children as special syntax rather than a standard prop, or suggesting a content prop instead of composition for wrapper components.
