The port property of the SharedWorker interface returns a MessagePort object used to communicate and control the shared worker.
Syntax
myWorker.port;
Value
A MessagePort object.
Example
The following code snippet shows creation of a SharedWorker object using the SharedWorker() constructor. Multiple scripts can then access the worker through a MessagePort object accessed using the SharedWorker.port property — the port is started using its start() method:
var myWorker = new SharedWorker("worker.js");
myWorker.port.start();
For a full example, see our Basic shared worker example (run shared worker.)
