Course overview

Lazy loading is a technique for loading images on the web only when they are needed to. It uses the idea of an image's appearance into the viewport which drives a procedure to load the image into view. Lazy loading is employed extensively around the web.

Most blogs, image galleries, and websites of other niches, use it to decrease loading times and save their user's device and network resources, such as battery and cellular data. Without lazy loading they will be left to simply eagerly load the images in the HTML which will in turn affect their sites' loading times, and ultimately their user base.

Not only does lazy loading improve the loading times of web pages but also makes sure that they look professional, elegant and leave an impression to the user that the developers of the site have put in at least some effort to design it. Lazy loading is so common out there that if you're about to start up a blog it will show in the suggestions for you to do. So why not start learning it today?
