Render Props

Render Props is a design pattern in React where a component's render logic is delegated to a function passed as a prop, typically named 'render' or 'children'. It allows components to share code and state logic without inheritance, enabling more flexible and reusable component composition. This pattern is commonly used for cross-cutting concerns like data fetching, state management, or UI behavior encapsulation.

Also known as: Render Prop Pattern, Function as Child, Children as Function, Render Callback, Render Method Prop

Why learn Render Props?

Developers should use Render Props when they need to share reusable logic across multiple components while maintaining separation of concerns and avoiding prop drilling. It's particularly useful for creating higher-order components (HOCs) alternatives, handling complex state interactions, or building libraries that require dynamic rendering based on external data. For example, it's ideal for tooltips, modals, or data providers where the rendering output needs to be customizable by the consumer.
