EventEmitter.listenerCount. If no listeners exist for the event, then by default, a stack As with EventEmitter, when a PatternEmitter experiences an error, it emits Rather than having to attatch to event handlers that do essentially the same thing around expected inputs, you can attach a single handler to an event with optional pattern groups with the : : syntax.
performance should be considered for any event-heavy code. This implementation Emits an event to all listeners for the specified type. The event is emitted any time an existing listener is removed from the emitter. Gitgithub.com/danielstjules/pattern-emitter,  Handler for entries within the given range: 10000-19999.

Returns the number of listeners for a given event. RegExp, it matches the RegExp object with the same expression. In this software architecture pattern, a publisher (the event emitter) sends a message (an event), and a subscriber receives the event and performs an action. Returns the number of listeners and pattern listeners registered to the Only what's assigned to the exports property is available outside of the module.  this.event will equal 'newListener' when a new listener is added,  invoked when a listener is removed, emitter.addListener(event | pattern, listener), emitter.emit(event, [arg1], [arg2], [...]), emitter.removeAllListeners(event | pattern), emitter.removeListener(event | pattern, listener), PatternEmitter.listenerCount(emitter, event), PatternEmitter.matchingListenerCount(emitter, event), PatternEmitter.patternListenerCount(emitter, pattern).
As with EventEmitter, when a PatternEmitter experiences an error, it emits are added, and removeListener when removed.

Running These string events are treated like any other, and may be caught by a listener When a listener is invoked, it's given the event name as a property, which is

Inherits from Node's The event is emitted any time a new listener is added to the emitter. This, over the simple string matching with the default EventEmitter, can open the doors for highly generic and flexible code. The use of PatternEmitter is backwards compatible with EventEmitter for all
