JS Party: JavaScript, CSS, Web Development

Getting a pulse on your Core Web Vitals 🩺


Listen Later

This week, Amal and Nick are joined by Rick Viscomi and Annie Sullivan from the Chrome team to dive into Core Web Vitals, a set of performance metrics geared towards helping developers surface web page quality signals that are key to delivering great user experiences.

We deconstruct the different vitals and learn how they are helpful, as well as introduce the newest vital to hit the scene, Interaction to Next Paint (INP). Join us for a fun and nerdtastic discussion as we dive into the humbling universe of web performance!
