Fantastic Mr. Function
summary
Live JavaScript coding that proves functions are the core: shows a J's flip 6‑character 120KB FizzBuzz hack, implements map/filter via reduce to show reduce can express mapping, filtering and folding, builds reusable abstractions (map, filter, reduce) from plain loops, and demos higher‑order utilities that return functions — a logger wrapper and a memoize decorator that actually cache results and suppress duplicate work. Historical context motivates why functions matter.
