The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on.
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).
This implementation accepts a settings object of type EventListenerOptions.

Returns the CacheStorage object associated with the current context.
Returns the CacheStorage object associated with the current context. This object enables functionality such as storing assets for offline use, and generating custom responses to requests.

The close() method of the WorkerGlobalScope interface discards any tasks queued in the WorkerGlobalScope's event loop, effectively closing this particular scope.
Accepts a variety of different image sources, and returns a Promise which resolves to an ImageBitmap.
Accepts a variety of different image sources, and returns a Promise which resolves to an ImageBitmap. Optionally the source is cropped to the rectangle of pixels originating at (sx, sy) with width sw, and height sh.
Returns a boolean value that indicates whether a SharedArrayBuffer can be sent via a Window.postMessage() call.
Returns a boolean value that indicates whether a SharedArrayBuffer can be sent via a Window.postMessage() call.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().

The importScripts() method of the WorkerGlobalScope interface imports one or more scripts into the worker's scope.

The location read-only property of the WorkerGlobalScope interface returns the WorkerLocation associated with the worker.
The location read-only property of the WorkerGlobalScope interface returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.
The navigator read-only property of the WorkerGlobalScope interface returns the WorkerNavigator associated with the worker.
The navigator read-only property of the WorkerGlobalScope interface returns the WorkerNavigator associated with the worker. It is a specific navigator object, mostly a subset of the Navigator for browsing scopes, but adapted to workers.
The onerror property of the WorkerGlobalScope interface represents an EventHandler to be called when the error event occurs and bubbles through the Worker.
The onlanguagechange property of the WorkerGlobalScope interface represents an EventHandler to be called when the languagechange event occurs and bubbles through the Worker.
The onoffline property of the WorkerGlobalScope interface represents an EventHandler to be called when the offline event occurs and bubbles through the Worker.
The ononline property of the WorkerGlobalScope interface represents an EventHandler to be called when the online event occurs and bubbles through the Worker.
Returns the origin of the global scope, serialized as a string.

Enqueues a microtask—a short function to be executed after execution of the JavaScript code completes and control isn't being returned to a JavaScript caller, but before handling callbacks and other tasks.
Enqueues a microtask—a short function to be executed after execution of the JavaScript code completes and control isn't being returned to a JavaScript caller, but before handling callbacks and other tasks.
This lets your code run without interfering with other, possibly higher priority, code, but before the browser runtime regains control, potentially depending upon the work you need to complete.

The self read-only property of the WorkerGlobalScope interface returns a reference to the WorkerGlobalScope itself.
The self read-only property of the WorkerGlobalScope interface returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope, SharedWorkerGlobalScope, or ServiceWorkerGlobalScope.

The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by Window objects — in this case event handlers, the console or the associated WorkerNavigator object. Each WorkerGlobalScope has its own event loop.
This interface is usually specialized by each worker type: DedicatedWorkerGlobalScope for dedicated workers, SharedWorkerGlobalScope for shared workers, and ServiceWorkerGlobalScope for ServiceWorker. The self property returns the specialized scope for each context.
