+
+<p>The <code><strong>WorkerGlobalScope</strong></code> interface of the <a href="/en-US/docs/Web/API/Web_Workers_API">Web Workers API</a> is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by {{domxref("Window")}} objects — in this case event handlers, the console or the associated {{domxref("WorkerNavigator")}} object. Each <code>WorkerGlobalScope</code> has its own event loop.</p>
+
+<p>This interface is usually specialized by each worker type: {{domxref("DedicatedWorkerGlobalScope")}} for dedicated workers, {{domxref("SharedWorkerGlobalScope")}} for shared workers, and {{domxref("ServiceWorkerGlobalScope")}} for <a href="/en-US/docs/Web/API/ServiceWorker_API">ServiceWorker</a>. The <code>self</code> property returns the specialized scope for each context.</p>

+ <dt>{{domxref("WorkerGlobalScope.close()")}}</dt>
+ <dd>Discards any tasks queued in the <code>WorkerGlobalScope</code>'s event loop, effectively closing this particular scope. In newer browser versions, <code>close()</code> is available on <code>DedicatedWorkerGlobalScope</code> and {{domxref("SharedWorkerGlobalScope.close", "SharedWorkerGlobalScope")}} instead. This change was made to stop <code>close()</code> being available on service workers, as it isn't supposed to be used there and always throws an exception when called (see {{bug(1336043)}}).</dd>
+</dl>
+
+<h2 id="Example">Example</h2>
+
+<p>You won't access <code>WorkerGlobalScope</code> directly in your code; however, its properties and methods are inherited by more specific global scopes such as {{domxref("DedicatedWorkerGlobalScope")}} and {{domxref("SharedWorkerGlobalScope")}}. For example, you could import another script into the worker and print out the contents of the worker scope's <code>navigator</code> object using the following two lines:</p>
+
+<pre class="brush: js">importScripts('foo.js');
+console.log(navigator);</pre>
+
+<div class="note">
+<p>Since the global scope of the worker script is effectively the global scope of the worker you are running ({{domxref("DedicatedWorkerGlobalScope")}} or whatever) and all worker global scopes inherit methods, properties, etc. from <code>WorkerGlobalScope</code>, you can run lines such as those above without specifying a parent object.</p>
