ServiceWorkerRegistration.sync

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The sync property of the ServiceWorkerRegistration interface returns a reference to the SyncManager interface, which manages background synchronization processes.
