LazyLoad is a lightweight, flexible script that speeds up your website by deferring the loading of your below-the-fold images, backgrounds, videos, iframes and scripts to when they will enter the viewport. Written in plain "vanilla" JavaScript, it leverages IntersectionObserver, supports responsive images and enables native lazy loading.
