How does AngularJS handle large-scale caching architecture?

AngularJS uses client-side caching via services, $cacheFactory, and HTTP caching strategies.

Caching reduces redundant API calls and improves performance. AngularJS provides $cacheFactory for in-memory caching and $http caching for GET requests. At scale, caching strategies include TTL-based invalidation, stale-while-revalidate patterns, and distributed cache coordination with backend systems.
