The Power of Composition
summary
Clear claim: build large systems by composing tiny functions and types. Uses F# code: composition operator and pipe and compose operators, currying and partial application to turn multi-arg methods into composable one-arg functions, map/iterate for lists, and bind/monads to chain effectful steps. Shows a composable Roman‑numeral replacer and a carbonation FizzBuzz pipeline, then assembles reusable web parts into an object-free web application using Suave — a working demo that keeps IO at the edges and scales by composition.
