Eliminate Unused JavaScript Code
High Impact+25 points estimated
Why It Matters
104 KiB of unused JavaScript is blocking rendering and delaying LCP by 750ms, severely impacting Core Web Vitals.
How to Fix
Remove or lazy-load jQuery UI (60KB unused), DataTables (25KB unused), and Swiper (20KB unused) if not needed on initial load. Use code splitting to load libraries only when required. Consider replacing heavy libraries with lightweight alternatives.

AI Performance Analysis
This website has poor performance with a score of 61/100, indicating significant issues that are hurting user experience. The biggest problem is excessive unused JavaScript, particularly from libraries like jQuery UI and DataTables, which is wasting 104 KiB and delaying your Largest Contentful Paint by 750ms. Your site takes nearly 8 seconds to fully load (7.9s for LCP), which is far too slow for modern web standards. The quickest wins would be removing or deferring unused JavaScript code, optimizing your oversized images (which could save 155 KiB), and addressing render-blocking CSS files that are delaying initial page rendering by nearly 1 second.
