Interactive Development with the REPL

Interactive Development with the REPL focuses the intermediate track on decisions a Java engineer must make after the first syntax barrier is gone. Read these lessons as engineering checkpoints: what data shape is being moved, which boundary is stateful, and where Clojure should simplify rather than imitate the Java design.
