| The [ServiceWorker][1] object can be in several states. The `state` attribute |
| must return the current state, which must be one of the following values |
| defined in the [ServiceWorkerState][2] enumeration: |
| |
| `"installing"`: |
| The Service Worker represented by the [ServiceWorker][1] object has entered |
| and is running the steps in the [installation process][3]. During this |
| state, `e.waitUntil(p)` can be called inside the `oninstall` event handler |
| of the associcated [ServiceWorkerGloberScope][4] object to extend the life |
| of the [installing worker][5] until the passed [Promise][6] resolves |
| successfully. This is primarily used to ensure that the Service Worker is |
| not active until all of the core caches are populated. |
| `"installed"`: |
| The Service Worker represented by the [ServiceWorker][1] object has |
| completed the steps in the [installation process][3]. The Service Worker in |
| this state is considered the [worker in waiting][7]. |
| `"activating"`: |
| The Service Worker represented by the [ServiceWorker][1] object has entered |
| and is running the steps in the [activation process][8]. During this state, |
| `e.waitUntil(p)` can be called inside the `onactivate` event handler of the |
| associated [ServiceWorkerGloberScope][9] object to extend the life of the |
| activating [active worker][10] until the passed [Promise][6] resolves |
| successfully. Note that no [functional events][11] are dispatched until the |
| state becomes `"activated"`. |
| `"activated"`: |
| The Service Worker represented by the [ServiceWorker][1] object has |
| completed the steps in the [activation process][8]. The Service Worker in |
| this state is considered the [active worker][10] ready to [control][12] the |
| documents in matching scope upon subsequence [navigation][13]. |
| `"redundant"`: |
| A newly created Service Worker [registration][14] is replacing the current |
| [registration][14] of the Service Worker. |
