Worker: error event

The error event of the Worker interface fires when an error occurs in the worker.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('error', event => { });

onerror = event => { };

A generic Event.

The following code snippet creates a Worker object using the Worker() constructor and sets up an onerror handler on the resulting object:

var myWorker = new Worker('worker.js');

myWorker.onerror = function(event) {
  console.log('There is an error with your worker!');
}
