emitterEmitter on which events can be listened to.
+Events that can currently be listened to:
+'full'
: Emitted when the pool is dynamic and the number of workers created has reached the maximum size expected.'ready'
: Emitted when the number of workers created in the pool has reached the minimum size expected and are ready.'busy'
: Emitted when the number of workers created in the pool has reached the maximum size expected and are executing at least one task.'error'
: Emitted when an uncaught error occurs.'taskError'
: Emitted when an error occurs while executing a task.When we receive a message from the worker we get a map entry and resolve/reject the promise based on the message.
