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).

The caches read-only property of the WorkerGlobalScope interface returns the CacheStorage object associated with the current worker context.
The caches read-only property of the WorkerGlobalScope interface returns the CacheStorage object associated with the current worker context. This object enables service worker 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.

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.
MDN
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 onmessage property of the DedicatedWorkerGlobalScope interface represents an EventHandler to be called when the message event occurs and bubbles through the Worker — i.e.
The onmessage property of the DedicatedWorkerGlobalScope interface represents an EventHandler to be called when the message event occurs and bubbles through the Worker — i.e. when a message is sent to the worker using the Worker.postMessage method.

The postMessage() method of the DedicatedWorkerGlobalScope interface sends a message to the main thread that spawned it.
The postMessage() method of the DedicatedWorkerGlobalScope interface sends a message to the main thread that spawned it. This accepts a single parameter, which is the data to send to the worker. The data may be any value or JavaScript object handled by the structured clone algorithm, which includes cyclical references.
The main scope that spawned the worker can send back information to the thread that spawned it using the Worker.postMessage method.
MDN
The object to deliver to the main thread; this will be in the data field in the event delivered to the Worker.onmessage handler. This may be any value or JavaScript object handled by the structured clone algorithm, which includes cyclical references.
An optional array of Transferable objects to transfer ownership of. If the ownership of an object is transferred, it becomes unusable (neutered) in the context it was sent from and it becomes available only to the main thread it was sent to.
Removes the event listener previously registered with EventTarget.addEventListener.

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.
MDN
The DedicatedWorkerGlobalScope object (the Worker global scope) is accessible through the self keyword. Some additional global functions, namespaces objects, and constructors, not typically associated with the worker global scope, but available on it, are listed in the JavaScript Reference. See also: Functions available to workers.
