Pass in optional write and end methods. through takes care of pause/resume logic if you use this.queue(data) instead of this.emit('data', data). Use this.pause() and this.resume() to manage flow. Check this.paused to see current flow state. (write always returns !this.paused). . This function is the basis for most of the synchronous streams in event-stream. . Node.js is an event-based server-side JavaScript engine.
