range

Finds smallest and largest entries. 🏃 📼 📦 🌔 📒

Similar: min, max, range.

array.range(x, [fc], [fm]);
// x:  an array
// fc: compare function (a, b)
// fm: map function (v, i, x)
// --> [smallest, largest]

const array = require("extra-array");

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

array.range(x, (a, b) => Math.abs(a) - Math.abs(b));
// [ [ 0, 1 ], [ 3, -4 ] ]

array.range(x, null, v => Math.abs(v));
// [ [ 0, 1 ], [ 3, -4 ] ]
