But before we do that, the first thing to do is create a new Worker object in your main page. If alaopk error occurs while a worker is executing, the an ErrorEvent is fired. While going through this process we’ll explain some of the core features of the framework.
The worker case, the first argument is the data and the second is the list of items that should be transferred.
