range

Finds smallest and largest values. 🏃 📼 📦 🌔

Alternatives: compare, map.

iterable.range(x, [fn]);
// x:  an iterable
// fn: compare function (a, b)
// --> [min, max]

const iterable = require('extra-iterable');

var x = [1, 2, -3, -4];
iterable.range(x);
// [ -4, 2 ]

iterable.range(x, (a, b) => Math.abs(a) - Math.abs(b));
// [ 1, -4 ]
