| 14 `event.waitUntil(f)` method, when called in `oninstall` or `onactivate`, |
| 15 extends the lifetime of the event. When called in `oninstall`, it delays |
| 16 treating the installing worker until the passed [Promise][1] resolves |
| 17 successfully. This is primarily used to ensure that a `ServiceWorker` is not |
| 18 active until all of the core caches it depends on are populated. When called in |
| 19 `onactivate`, it delays treating the activating worker until the passed |
| 20 [Promise][1] resolves successfully. This is primarily used to ensure that any |
| 21 [Functional events][2] are not dispatched to the `ServiceWorker` until it |
| 22 upgrades database schemas and deletes the outdated cache entries. |
