    In this situation, lazy loading, a popular technique used to defer the loading of resources until needed, can be implemented to defer rendering a component unless the user scrolls down to bring it into the viewport. One of the most popular lazy loading libraries in React, react-lazyload, makes use of conditional rendering to render components only when they are scrolled into the viewport of the user's browser or, in other words, are visible to the user.

    Developers also employ alternative methods for lazy loadings, such as the scroll event listener, besides the Intersection Observer API and the loading property. Unlike the Intersection Observer API, which only monitors the elements targeted for lazy loading, developers attach a scroll event listener to every element on the page. Once the element marked for lazy loading is within the visibility range of the user, a function is invoked to switch the image or video URL with the attribute previously holding it, just like with the Intersection Observer API. This approach is costly for a web project. As the developer seeks to optimise page load by integrating lazy loading to some elements on the webpage, the developer slows down the page's performance due to multiple firing of an event as the function meets each element. Moreover, packages for JavaScript that deal with lazy loading exist. For instance, the LazyLoad library uses the Intersection Observer API, a lightweight JavaScript library. It supports many lazy loading features, such as preloading, responsive image loading, and custom loading animations. Additional lazyloading libraries include Yall.js, Lozad.js, LazyLoad XT for jQuery, and many more.
