Practice translating loops into reduce/pipelines and writing stack-safe recursion where it fits.
This section is about building muscle memory.
You will take problems that Java developers normally solve with loops and mutable variables and solve them in Clojure using:
map / filter)reduce)loop/recur)Practical tip: do the examples in a REPL. The fastest way to learn iteration in Clojure is to evaluate small variations and inspect the intermediate values.
The goal is not to be clever. It is to pick the simplest iteration shape and make the data flow obvious.
