All I needed for FP I learned in High School Algebra
summary
Maps algebraic properties onto everyday code and shows how to derive and enforce them: uses Clojure examples (reduce, tuples for sum/count) to implement an associative aggregator for averages and adds an identity to make it a monoid, uses property testing with test.check to assert commutativity and grouping, demonstrates idempotent updates for button/state via hashmaps to achieve idempotence, and explains how these properties solve distributed issues like out-of-order delivery, duplicates, and safe serialization/deserialization.
