Angular - Performance OptimizationYou notice your Angular bundle is very large. Which combination of actions will best reduce the bundle size?ADisable Ahead-of-Time compilation and enable source mapsBUse lazy loading for modules and remove unused importsCAdd more third-party libraries and increase polyfillsDIncrease the number of components and servicesCheck Answer
Step-by-Step SolutionSolution:Step 1: Identify techniques to reduce bundle sizeLazy loading loads modules only when needed, and removing unused imports cuts unnecessary code.Step 2: Evaluate options for reducing sizeUse lazy loading for modules and remove unused imports correctly combines these effective methods. Other options add size or disable optimizations.Final Answer:Use lazy loading for modules and remove unused imports -> Option BQuick Check:Lazy loading + clean imports = smaller bundle [OK]Quick Trick: Lazy load and clean imports to shrink bundle [OK]Common Mistakes:Adding more libraries increases sizeDisabling AOT slows app and increases sizeAdding components without optimization
