Functional Design Patterns
Functional Design Patterns helps Java engineers apply functional Clojure through explicit data flow, controlled effects, tests, and JVM-aware trade-offs.
Functional Design Patterns frames Design Patterns as a practical design checkpoint for Java engineers writing Clojure. Use these lessons to connect functional concepts to JVM code you can test, review, operate, and evolve without falling back into hidden mutable state.
| Checkpoint |
What to verify |
| Concept boundary |
You can explain where Design Patterns changes the design compared with a class-oriented Java implementation. |
| Clojure shape |
You can identify the values, functions, namespaces, and effect boundaries involved. |
| Production risk |
You can name the main review risk: accidental state, lazy resource retention, unclear interop, macro complexity, weak tests, or poor observability. |
