Lazy Loading

Lazy loading is a performance optimization technique used in web development to defer the loading of non-essential resources until they are actually needed. Instead of loading all resources, such as images, videos, or scripts, at the initial page load, lazy loading delays their loading until the user scrolls to the point where they are required. This approach significantly reduces the initial loading time of a webpage, improving user experience by making the site feel faster and more responsive.

The primary benefit of lazy loading is the reduction in the amount of data that needs to be downloaded when a page is first accessed, which is particularly important for users on slow networks or mobile devices. By prioritizing the loading of visible content, lazy loading also helps reduce the strain on server resources, making the website more scalable and efficient.
