Lazy Loading is a design pattern used in web development to improve performance by loading only the necessary resources when they are needed. Instead of loading all images or data at once when a page is opened, Lazy Loading waits until the user scrolls down or interacts with the page. This means that the initial load time is faster, making the user experience smoother. By implementing Lazy Loading, websites can save bandwidth and reduce server load, as only the content that is currently in view is fetched. This technique is especially useful for pages with many images or long lists, ensuring that users can access information quickly without unnecessary delays.
