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| upgrades database schemas and deletes the outdated cache entries.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