Obtain values not present in both arrays.
Similar: union, intersection, difference, symmetricDifference.
function symmetricDifference(x, y, fc, fm)
// x: an array
// y: another array
// fc: compare function (a, b)
// fm: map function (v, i, x)⏱️ Compare function ⇒ O(n²).
const xarray = require('extra-array');
var x = [1, 2, 3, 4];
var y = [3, 4, 5];
xarray.symmetricDifference(x, y);
// → [ 1, 2, 5 ]
var y = [-3, -4, -5];
xarray.symmetricDifference(x, y);
// → [
// 1, 2, 3, 4,
// -3, -4, -5
// ]
xarray.symmetricDifference(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// → [ 1, 2, -5 ]
xarray.symmetricDifference(x, y, null, v => Math.abs(v));
// → [ 1, 2, -5 ]
