Describe the Service Worker lifecycle and cache versioning
Tests your grasp of the Service Worker lifecycle and cache versioning. A strong answer sequences register, install, activate, and fetch; notes install precaches assets while activate purges old caches and finalizes takeover.
Tests whether you understand the Service Worker lifecycle and cache versioning strategy beyond simple API memorization. A strong candidate sequences registration, installation, activation, and fetch interception; explains that the install event precaches core assets into CacheStorage, while the activate event cleans up obsolete caches from previous versions and completes the takeover from the old worker. Red flag: claiming the new worker immediately controls pages without mentioning the waiting phase, skipWaiting, or clients.claim.
