The Lord of Collection Functions - The Fellowship of Kotlin
summary
Concrete claims and runnable examples: the Kotlin standard library collection functions replace imperative loops and mutable state with map then flatten vs flatMap, show that reduce vs fold differ by initial value and result type, and that zip drops unmatched (fellowship of nine zips with six enemies leaves three idle). Demos use a shared “fellowship” dataset, sum ages, count four hobbits, compute a 50-point healing total, show chunked calling windowed, and publish full code and extended slides via the provided link tree — examples execute but a flaky unit test surfaces.
