About
Native lazy loading is a technique to load non-critical images and iframes marked with the loading="lazy" attribute only when needed.
The rel="prefetch" attribute on 
HTML <link> elements tells the browser to download resources that are likely to be needed for future navigation when the current page is idle.
It allows caching resources in advance with low priority and is commonly used for next-page documents, scripts, styles, or assets in multi-step flows.
