range

Finds smallest and largest entries. 🏃 📼 📦 🌔 📒

Similar: min, max, range.

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

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

var x = {a: 1, b: 2, c: -3, d: -4};
object.range(x);
// [ [ 'd', -4 ], [ 'b', 2 ] ]

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

object.range(x, null, v => Math.abs(v));
// [ [ 'a', 1 ], [ 'd', -4 ] ]
