web.workers.ExtendableEvent
The ExtendableEvent interface extends the lifetime of the install activate events dispatched on the global scope as part of the worker lifecycle. This ensures that any functional events (like are not dispatched until it upgrades database schemas and deletes outdated cache entries.

wait-untilcljs
(wait-until this promise)Method.
The extendableEvent.waitUntil() method tells the event dispatcher work is ongoing. It can also be used to detect whether that work successful.
