import { MonoidNumberSum } from "./number.ts";
import { getRightMonad, pair } from "./pair.ts";
import { pipe } from "./fn.ts";

const Monad = getRightMonad(MonoidNumberSum);

const ageOneYear = (name: string) => pair(name, 1);

const result = pipe(
  pair("Brandon", 36), // Pair(Name, Age)
  Monad.chain(ageOneYear),
  Monad.chain(ageOneYear)
); // ["Brandon", 38]
