Summary

Jonathan Graham presents how to implement our own versions of the Clojure functions reduce, count, filter, map and pmap. The pace starts gently for those with little Clojure experience to follow, but then dives deep to provide a full understanding.

  • Error on slides

    Looks like the my-reduce function from slides has an error in it. The recursive call should be (my-reduce f (f (first coll)) (rest coll)). Also this this function will blow the stack pretty soon :P (I'm only 7 mins in the talk though, he will probably point that out.)

    Oh, my mistake. There should be a val in (f val (first coll)).
