Pure Functional

+Pure Functional programming treats computation as the evaluation of mathematical functions, rigorously avoiding [Side Effects](/wiki/side_effects) and shared, mutable state. This paradigm fosters programs that are inherently easier to reason about, test, and parallelize, relying on [Immutability](/wiki/immutability) to ensure predictable behavior.
