Lazy-loading might make above-the-fold pictures load slower (longer LCP) as a result of the browser begins the obtain later and since the browser first has to execute the JavaScript.

One other JavaScript challenge entails code that’s giant or pointless for the web page. In different phrases, code bloat. There are good assets for resolving these points on the internet. Nevertheless, on this weblog, we’ll concentrate on picture issues.
