array.symmetricDifference(x, y, [fc], [fm]);
// x:  an array

// fc: compare function (a, b)
// fm: map function (v, i, x)

:stopwatch: Compare function => O(n²).

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

var x = [1, 2, 3, 4];
var y = [3, 4, 5];

// [ 1, 2, 5 ]

var y = [-3, -4, -5];

// [
//    1,  2,  3, 4,
//   -3, -4, -5

array.symmetricDifference(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// [ 1, 2, -5 ]

array.symmetricDifference(x, y, null, v => Math.abs(v));
// [ 1, 2, -5 ]
