Why is my site’s JavaScript affecting loading speed?

Heavy or poorly-optimized JavaScript can slow page loads, particularly if scripts run before content renders.

If JavaScript affects loading speed, consider lazy-loading scripts or deferring them until after the main content loads. Using minified code and consolidating multiple scripts reduces processing time. Tools like Google PageSpeed Insights help identify specific JavaScript files slowing the page. Consider using asynchronous loading or breaking down large scripts into smaller, manageable chunks to improve site performance.
