Some questions about frontend development that might be in your next job interview. The questions were formulated by @mauvieira, a super senior fullstack developer

• What are the strategies we can use to optimize the performance of web applications?

  • CDNs, GraphQL (maybe) to reduce overfetching, improve backend performance, use SSR and/or SSG, lazy loading for loading assets only when it's needed, minimize and compress HTML, CSS and JS files, and optimize images by compressing and resizing them.

• What are Web Vitals (LCP, FID, CLS)? And how are they applied in the real world?
