Tricky Clojure Functions: partial, comp, juxt and more

Hey there! So, in this video, we're gonna walk through some functions that might give you a bit of trouble, especially if you're new to Clojure or functional programming. But don't worry, because even though they can be a bit tricky, they're actually pretty useful, and chances are you'll come across them in real-world code sooner or later. Let's dive in!

Good afternoon. Thanks for the great video, as always. I would like to add to share my experience in team. Never use comp fn in code when it needs to be read backwards. It's best not to use comp at all. This tool is applicable when the issue of performance arises, and in this case it should be used together with transducers, which already greatly raises the bar for the reader. If you get to this situation, don’t forget to generously describe everything with comments. And in the case of transducers, the comp needs to be read in the usual order. Like (sequence (comp (map :v) (map inc)) [{:v 1} {:v 2} {:v 3}]).

Thanks for the video! Very clear explanations. I would like to add regarding the juxt function, that it comes habdy when you want to pass the same argument to different functions.

I’m new to clojure. I was trying to find a flatten function. Maybe this is unconventional, but I used “mapcat identity coll”.

I wasn't aware about map operating in chunks... where can I read more like this?
