var x = [-2, -3, 1, 4];
array.sort(x);
// [ -3, -2, 1, 4 ]

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

var x = ['D', 'B', 'a', 'c'];
array.sort(x);
// [ 'B', 'D', 'a', 'c' ]

array.sort(x, (a, b) => a.toLowerCase().localeCompare(b.toLowerCase()));
// [ 'a', 'B', 'c', 'D' ]
