🧒 Explain like I'm 5
Imagine you have a favorite toy that you sometimes play with at home and sometimes take to the park. Service Worker caching strategies are like deciding whether to grab the toy from your room first (Cache-First), ask your friend if they have it first (Network-First), or use an old toy while checking if a new one is available (Stale-While-Revalidate). Cache versioning is like putting a sticker on your toy box so you know which toys are the newest and can throw away old ones.
