Purity is better than side effects Pure functions create predictable, testable code. Functions depend only on inputs and produce no side effects.

Immutability is better than mutation Data that cannot change eliminates entire categories of bugs. State cannot be modified; concurrent operations become naturally safe.

Composition is better than monoliths Small, focused functions combined thoughtfully solve complex problems elegantly.

Master functional programming principles and patterns including purity, immutability, composition, higher-order functions, algebraic data types, functors, monads, and effect management. Use when working with functional paradigms, pure functions, immutable data structures, function composition, type-safe error handling, or implementing functional patterns like map/filter/reduce, currying, partial application, recursion, lazy evaluation, or referential transparency.
