- Core Web Vitals are three metrics: First Input Delay, Cumulative Layout Shift, and Largest Contentful Paint.
- The way to measure performance is by reasoning about long tasks in JavaScript performance.
- Chrome DevTools and Lighthouse have been working together to provide better support for user flows and performance metrics.
- The recorder conversion package allows for converting recorded user flows to Puppeteer scripts.
- The performance of a user flow can be measured using the Performance Insights experiment.
- The future of performance tooling will prioritize user-centricity, actionable guidance, and contextual understanding.
- The impact of performance on user experience is crucial, and improving performance is a journey.
