A library to lazy load images using Intersection Observer
If you'd like to learn more about this code, I've written up a full blog post on my blog.
This library was also featured on the 2017 Performance Calendar - for more details, please see this link.
For a live demo, please visit deanhume.github.io/lazy-observer-load.
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.
