Get ready for a web performance deep dive! In this session, we'll demystify INP (Interaction to Next Paint), the new kid on the block replacing FID in March 2024, drawing insights from analyzing data across 10 million websites at Wix. As INP de-facto becomes a Core Web Vitals metric, understanding its implications is crucial for optimizing user experiences.

Alongside INP, we'll introduce LoAF (Long Animation Frames) API, showcasing practical insights derived from our analysis. No jargon, just real-world data and tips on leveraging INP and LoAF for faster, more efficient web experiences. Join us for a straightforward exploration of web performance essentials with a unique perspective drawn from a massive dataset at Wix.
