Answer key and explanations20 questions The quiz above draws 20 questions at random from these 30, so a second attempt will not be the same run. Everything in the pool is listed here. 1. What is Redux? AnswerCentralized state management using a single store, actions, and reducers 2. What is a selector in Redux? AnswerA function that extracts and derives specific data from the Redux store 3. What is Zustand? AnswerA minimalist state management library using a hooks-based API 4. What is the React Context API? AnswerA built-in feature to share data across components without prop drilling 5. What is code splitting? AnswerDividing the application bundle to lazy-load specific components or routes 6. What is tree shaking? AnswerThe removal of unused exports from the final JavaScript bundle 7. What is bundle analysis? AnswerThe use of tools to identify large dependencies and optimization targets 8. What are web vitals? AnswerA set of core metrics (LCP, FID, CLS) used to measure user experience 9. What is LCP (Largest Contentful Paint)? AnswerThe time it takes to render the largest visible element in the viewport 10. What is FID (First Input Delay)? AnswerThe time between a user interaction and the browser's response 11. What is CLS (Cumulative Layout Shift)? AnswerA metric measuring the visual stability of a page during the loading process 12. What is preloading? AnswerA browser hint used to fetch high-priority resources early in the lifecycle 13. What is prefetch? AnswerA low-priority browser hint to fetch resources for future navigation 14. What is lazy loading? AnswerDeferring the loading of non-critical resources until they are visible 15. What is virtual scrolling? AnswerA technique that renders only the items currently visible in the viewport 16. What is memoization in React? AnswerCaching the results of expensive computations or component renders 17. What is the useCallback hook? AnswerA hook that memoizes function references to prevent child re-renders 18. What is the useReducer hook? AnswerA hook for managing complex state through actions and a reducer function 19. What is Recoil? AnswerA state management library that uses a graph-based atom architecture 20. What is Jotai? AnswerA minimalist state management library focused on atomic state units 21. What is render optimization? AnswerReducing wasted work by using memoization, keys, and batching 22. What is hydration in SSR? AnswerThe process of attaching event listeners to server-rendered HTML markup 23. What is critical CSS? AnswerInline styles required for the first paint of the visible viewport 24. What is the RAIL model? AnswerA performance framework focusing on Response, Animation, Idle, and Load 25. What is INP (Interaction to Next Paint)? AnswerA metric measuring the time from an interaction to the next visual update 26. What are Web Workers? AnswerA feature for running scripts in a separate background thread from the UI 27. What is component composition? AnswerA pattern of building complex UIs by combining small, focused components 28. What is the render prop pattern? AnswerA technique for sharing code by passing a function as a component prop 29. What is a higher-order component (HOC)? AnswerA function that takes a component and returns a new enhanced component 30. What is an error boundary in React? AnswerA class component that catches JavaScript errors in its child component tree ## Tags [#Frontend](/quizzes/tags/frontend)[#Performance](/quizzes/tags/performance)[#Architecture](/quizzes/tags/architecture) ## Share [Facebook](https://facebook.com/sharer/sharer.php?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz "Share on Facebook")[Twitter](https://twitter.com/intent/tweet/?text=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz "Share on Twitter")[LinkedIn](https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz&title=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance&summary=Master%20advanced%20frontend%20architecture%3A%20state%20management%20\(Redux%2C%20Zustand\)%2C%20performance%20optimization%2C%20code%20splitting%2C%20lazy%20loading%2C%20and%20responsive%20design%20patterns.&source=https://mkabumattar.com "Share on LinkedIn")[WhatsApp](https://wa.me/?text=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance%20https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz "Share on WhatsApp")[Telegram](https://t.me/share/url?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz&text=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance "Share on Telegram")[Reddit](https://www.reddit.com/submit?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz&title=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance "Share on Reddit")[Hacker News](http://news.ycombinator.com/submitlink?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz&t=Advanced%20Frontend%20Patterns%3A%20State%20Management%20%26%20Performance "Share on Hacker News")[Pinterest](https://pinterest.com/pin/create/button/?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-frontend-patterns-quiz&media=&description=Master%20advanced%20frontend%20architecture%3A%20state%20management%20\(Redux%2C%20Zustand\)%2C%20performance%20optimization%2C%20code%20splitting%2C%20lazy%20loading%2C%20and%20responsive%20design%20patterns.
