The Worker.onmessage property represents an EventHandler, that is a function to be called when the message event occurs.
The Worker.onmessage property represents an EventHandler, that is a function to be called when the message event occurs. These events are of type MessageEvent and will be called when the worker calls its own postMessage() method: it is the way that a Worker has to give back information to the thread that created it.

The Worker.terminate() method immediately terminates the Worker.

The Worker interface represents a background task that can be easily created and can send messages back to their creators. Creating a worker is as simple as calling the Worker() constructor, specifying a script to be run in the worker thread.
Of note is the fact that workers may in turn spawn new workers as long as those workers are hosted within the same origin as the parent page. In addition, workers may use XMLHttpRequest for network I/O, with the exception that the responseXML and channel attributes on XMLHttpRequest always return null.
