How does Angular improve performance?

Question

Accepted Answer

Angular enhances performance through features like Ahead-of-Time compilation, change detection strategies, and lazy loading.

Ahead-of-Time (AOT) Compilation: Angular compiles the application during the build process, reducing the amount of work needed at runtime and improving load times.
Change Detection Strategy: Angular uses a hierarchical change detection mechanism, allowing developers to optimize performance by choosing between Default and OnPush strategies.
Lazy Loading: Angular allows modules to be loaded on demand, which reduces the initial load time and improves performance by only loading necessary resources.
TrackBy in ngFor: Using TrackBy with ngFor helps Angular identify which items have changed, preventing unnecessary re-renders and improving rendering performance.
Service Workers: Angular supports service workers for caching assets and API responses, enabling faster load times and offline capabilities.
