Worker: error event

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!');
}
