With web traffic becoming predominantly mobile, performance is a priority in development. With one click, developers can now generate a Lighthouse performance report and score.

Can you dive into the details of the report results and understand where to make updates?? This is a talk about the subtleties of the Lighthouse performance score, understanding the speed metrics and how to parse the remainder of the performance audit to improve page loads and ux.
