In the Ajax coding, Lazy Loading is a term that loads content in a very approach that accelerates the rendering method on a web site. rather than awaiting all content to load from a database or web server, lazy loading permits you to show text and background elements whereas alternative containers wait to load a lot of resource-intensive content. As a result, the user sees content inside seconds whereas alternative parts, like reports or pictures, are still loading. It improves the perceived load times and engages users instead of losing them to poor performance.
