Web worker tasks that consume more CPU resources

A small example of Web worker, which is suitable for getting started, is recommended to start a service to develop. You can use node's anywhere.

When a web worker passes a message, the code in the event listener is executed. Data from Event.data is stored in the event.data.
Then we can take and receive messages from the Web worker and add a "onmessage" event listener to the Web worker.
/demo_worker.js
