Prefetching, Preloading and Prerendering in HTML

The article discusses the differences between prefetching, preloading, and prerendering in HTML, which are techniques aimed at improving the performance of web page loading. Prefetching is used to download resources that may be needed in the future, thus reducing waiting time when a user decides to utilize them. On the other hand, preloading allows for the early loading of essential resources necessary to display the page. The article highlights that preloading is a more aggressive technique compared to prefetching, but it also brings greater benefits. It's important to note that excessive use of these techniques can affect performance, as they may introduce additional network traffic and burden the server. The final part of the article focuses on prerendering, which involves creating a copy of the page in the background, allowing for immediate display when the user clicks a link. Understanding these techniques can significantly enhance user experiences and speed up web page loading.
