// fm: map function (v, i, x)

⏱ Compare function => O(n²).

const array = require('extra-array');
 
var x = [1, 2, 3, 4];
var y = [3, 4, 5];
array.symmetricDifference(x, y);

// [
//    1,  2,  3, 4,
//   -3, -4, -5
// ]
 
array.symmetricDifference(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// [ 1, 2, -5 ]
