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:

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

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