// x:  an array
// y:  another array
// fc: compare function (a, b)
// fm: map function (v, i, x)
// → x<y: -1, x=y: 0, x>y: 1

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

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

var y = [1, 2];
array.compare(x, y);
// 0

var y = [1, -2];
array.compare(x, y);
// 1

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

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