My mental model of Clojure transducers
I’ve been programming in Clojure for a long time, but I haven’t been using transducers much. I learned to mechanically transform (into [] (map f coll)) to (into [] (map f) coll) for a slight performance gain, but not much beyond that.

Code the shortest path first
There is a strange thing that I noticed as I progressed from a junior engineer to mid-career to senior.
