How does it identify performance bottlenecks?

It utilizes the React Profiler, bundle analysis tools, and Core Web Vitals metrics to pinpoint specific areas where the application is lagging.

Does it support modern build tools like Vite?

While it includes Webpack-specific patterns, the core principles of bundle analysis and code splitting are applicable to Vite, Rollup, and other modern bundlers.

Will this skill help with large datasets?

Absolutely. It specializes in runtime performance techniques like windowing (virtual lists) and debouncing to handle large amounts of data efficiently.

Can this skill help improve my site's SEO?

Yes, by optimizing Core Web Vitals and page load speeds, this skill helps improve the metrics that search engines use for ranking.
