Hi Joel,

I'm one of those noobs, but trying my very best not to be. I am trying to teach myself functional programming in JavaScript and I have come upon the subject of transducers. This code looks very similar; can you confirm that this code is, or is closely related to the concept of transducers.

Transducers are the next evolution. You would start with a list, and learn map, filter, reduce. Once you start applying multiple map/filter/reduces to a single list, you realize you are enumerating the list multiple times, which will slow down your application.

Transducers are a way to apply those multiple map/filter/reduces while enumerating the list one time.
