Infinite scrolling can optimize app performance and user experience by loading new content as users scroll through the app. However, traditional infinite scrolling has a common problem: unnecessary requests that can slow down apps due to excessive network calls and increased memory usage. Intersection Observer API overcomes these challenges by detecting when an element comes into view.
Master element visibility detection with the Intersection Observer API: a modern, browser-supported solution that outperforms scroll listeners, getBoundingClientRect polling, and jQuery by delivering efficient, flexible, and performant intersection tracking for multiple elements; power lazy loading, infinite scrolling, and on-scroll animations—e.g., loading e-commerce product images only when they enter the viewport.
