react-intersection-observer efficiently monitors React components for intersection with the viewport or another element. It provides a hook and a render prop component, simplifying the process of tracking when an element becomes visible. This is useful for lazy loading images, triggering animations, or performing other actions based on visibility. It leverages the Intersection Observer API for optimal performance and avoids resource-intensive polling. Its straightforward API makes managing intersection events within React applications smooth and performant.
