lanceharper / fold.js

Last active December 3, 2015 01:06 — forked from kpuputti/fold.js

Functional acrobatics using folds in JavaScript.

	/eslint-env es6 /

	// Inspired by the paper "A tutorial on the universality and
	// expressiveness of fold" by Graham Hutton (available at
	// http://www.cs.nott.ac.uk/~gmh/fold.pdf), implementing some generic
	// list handling functions in JavaScript in terms of `fold`.

	// Personally I had an enlightnening moment when I realised the
	// beautiful interplay of cons lists and foldr during the FP101x
	// Haskell course. JavaScript's syntax doesn't make this very apparent
