Prior to the introduction of React Hooks in 16.8, sharing stateful logic between components was challenging. The two primary techniques were Higher-Order Components (HOCs) and the Render Props Pattern.
The term "render prop" refers to a technique for sharing code between React components using a prop whose value is a function that returns a React element.
Instead of a component rendering a hardcoded piece of UI, it delegates rendering to the consumer by calling the function and passing its internal state as arguments:
Today, Custom Hooks (like useMousePosition() or useToggle()) have superseded render props for general logic sharing because hooks avoid "wrapper hell" and deep JSX nesting.
However, render props remain essential in modern React for:
Headless UI Libraries: (e.g. Downshift, React Virtualized, TanStack Table) where a component controls keyboard navigation and virtualization but leaves markup rendering entirely to the user.
Dynamic Slot Injection: Passing rendering callbacks for items inside complex virtualized lists or table cells.
