  CallgebraCallgebra
  The little algebra of callbacks.
  IntroductionIntroduction
  This package exports functions for composing callbacks. You can read about the idea in my Medium post about composable callbacks.
  UsageUsage
  NodeNode
  $ npm install --save callgebra
  On Node 12 and up, this module can be loaded directly with
  import or
  require. On Node versions below 12,
  require or the esm-loader can
  be used.
  import {of, callback} from 'callgebra'; callback (console.log) (of (42));

  There's a UMD file included in the NPM package, also available via jsDelivr:
  This file adds
  flutureProject to the global scope, or use CommonJS/AMD
  when available.
  const {of, callback} = require ('callgebra'); callback (console.log) (of (42));
  APIAPI
  type Callback a b = (b -> a) -> a
  of :: a -> Callback b a
  Creates a callback for a given return value.
  chain :: (a -> Callback c b) -> Callback c a -> Callback c b
  Sequence two callback-accepting functions.
  map :: (a -> b) -> Callback c a -> Callback c b
  Modify the return value of a callback.
  ap :: Callback c (a -> b) -> Callback c a -> Callback c b
  Apply the function returned by one callback to the value returned by another.
  callback :: (a -> b) -> Callback b a -> b
  Given a function and a Callback, runs the Callback using the function.
