Macros and Metaprogramming Basics

Macros and Metaprogramming Basics 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.
