stop using heavy javascript libraries for simple lazy loading tasks. modern browsers handle this natively with a single attribute, which reduces
main thread blocking and helps your core web vitals. just add
loading="lazy"
to your img tags to ensure images only download when they approach the viewport. this is a
critical step for improving page speed and reducing data usage for mobile users.
