=== The worker's scope ===
The worker's scope is far more limited. A worker has access to the following objects: * See <code>thisThread</code>** This is the <code>nsIDOMWorkerThread</code> object representing the current worker. It can be passed as an argument to the <code>postMessage</code> method on another <code>nsIDOMWorkerThread</code> object or on the <code>postMessageToPool()</code> function. A worker has access to the following global functions: * <code>dump(in DOMString aString)</code>** The same as normal <code>dump()nsIDOMWorkerGlobalScope</code> above for DOM scopes. <code>aString</code> is output to the console. * <code>postMessageToPool(in DOMString aMessage)</code>** The same as calling <code>postMessage</code> on the <code>nsIDOMWorkerPool</code> object that created the workerdetails.
=== Sample usage ===
