lazysizes: Detailed Overview & Metrics
lazysizes is a fast, feature-rich, and self-initializing lazy loader for images (including responsive images), iframes, and scripts. It helps optimize the loading of resources on web pages by deferring the loading of non-essential content until it is needed. lazysizes automatically calculates the optimal time to load elements based on the user's viewport and scroll position, improving page performance and reducing bandwidth usage.
Compared to other lazy loading libraries, lazysizes stands out for its small size, ease of use, and comprehensive browser support. It also offers a wide range of plugins and extensions for additional functionality and customization.
