ECHO.JS : SIMPLE JAVASCRIPT IMAGE LAZY LOADING

Echo.js, simple JavaScript image lazy loading via HTML5 data-attributes, superfast and standalone (jQuery free).Lazy-loading works by only loading the assets needed when the elements ‘would’ be in view, which it’ll get from the server for you upon request, which is automated by simply changing the image "src"attribute. This is also an asynchronous process which also benefits us.
