Skrip yang memblokir render
Mengapa penting
Scripts in the head without async or defer stop the browser from showing the page until they download and run.
Cara memperbaiki
- Add defer (or async) to scripts that are not needed for the first render.
- Move non-critical scripts to the end of the body.
Periksa dengan
- Page Speed Test – Lighthouse performance score, lab metrics and real-user Core Web Vitals for any page.
