// x:  lists
// y:  another lists
// fc: compare function (a, b)
// fm: map function (v, k, x)
// → x=y: 0, otherwise: -ve/+ve

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

var x = [['a', 'b'], [1, 2]];
var y = [['a', 'b', 'c'], [1, 2, 3]];
lists.compare(x, y);
// -1

var y = [['a', 'b'], [1, 2]];
lists.compare(x, y);
// 0

var y = [['a', 'b'], [1, -2]];
lists.compare(x, y);
// 1

lists.compare(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// 0

lists.compare(x, y, null, v => Math.abs(v));
// 0
