What is the purpose of render props in React?

• A. Render props allow sharing dynamic UI by passing a function as a prop that returns React elements.
• B. They replace components with higher-order functions.
• C. They are used to define CSS styles dynamically.
• D. They enable class-based components to use lifecycle methods.

Answer: (A)

Render props hinge on the idea of sharing UI logic by passing a function as a prop that returns React elements. A component receives this function (often called a render prop) and calls it to render its portion of the UI, allowing different rendering behavior while reusing the same component logic. This pattern makes it easy to encapsulate state and behavior in the component and let callers customize what gets rendered, without changing the component’s structure. It’s not about replacing components with higher-order functions, dynamically defining CSS, or enabling lifecycle methods in class components—the essence is injecting rendering logic via a function prop to produce UI that can vary across uses.
