Lots of interesting discussions about the #clojurex conference on the #clojurex channel. Would love to hear more thought and feedback

Morning All 🙂

Must say, May isn't looking too cheerful on the BBC News home page.

On-topic question. What is the fundamental difference between using doall followed by prn vs just doing the prn:

user=> (def v [:foo :bar :baz])
#'user/v
user=> (->> v (doall) (prn))
[:foo :bar :baz]
nil
user=> (->> v (prn))
[:foo :bar :baz]
nil
user=>

If I'm reading this right, (doall) forces eager evaluation so the entire data structure gets instantiated in memory.

I thought that was the case.

man ,slack is unwell today

yes, there is some kind outage today with slack.

Saturday's study group broadcast: https://youtu.be/pyIbP4BOGpQ A discussion 4Clojure challenge number 53. I think this is the hardest challenge I have come across, especially to do in a very functional way. I'll walk through a loop/recur approach (it gets a bit long) and then refactor to something a bit more functional.
