Explain Network First vs Cache First caching and when to use each
Tests matching caching strategy to asset freshness. Cache First serves static assets from the Cache API, falling back to network. Network First fetches fresh content, falling back to cache offline.
This tests whether you can pair a service worker caching strategy with asset freshness and offline needs. A strong answer explains Cache First checks the Cache API before the network, making it ideal for static assets like hashed JS bundles or images that rarely change. Network First tries the network and falls back to cache, suiting time-sensitive content like HTML or API responses that must be fresh but need offline resilience.
