Your question is Optimize React Bundle Sizes. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the performance implications of a large-scale React application and how you would optimize bundle sizes.
Discuss how JavaScript download, parsing, compilation, execution, rendering, and memory usage affect user-perceived performance. Explain how you would measure the problem and prioritize techniques such as code splitting, lazy loading, tree shaking, dependency analysis, compression, caching, and server-side rendering. Address tradeoffs, regression prevention, and how you would validate improvements in production.
