Orangutan
o-range-utan
A lazy range and list library for JavaScript. Heavily inspired by Haskell's lists and range syntax.
Requirements
Orangutan is currently distributed as an ES6 module using native iterators and generators. This means your environment must support function* and import/export syntax constructs.
Haskell vs Orangutan
There are many parallels between Orangutan and Haskell's lists/ranges
Ranges
// [1, 3..20]
range(1, 3, 20)
// [1..5]
range(1, undefined, 5)
// [3..]
range(3)
