Sorts an array in-place using natural order of its elements and returns the sorted array.

Unlike Array.prototype.sort(), Xnd's sort is not "built upon converting the elements into strings, then comparing their sequences of UTF-16 code units values" but instead any value that implements Comparable may be sorted.

const dates = [
  new Date("2020-12-14T12:12:07"),
  new Date("2020-12-13T12:12:07"),
];

dates.sort(); // coerces dates to strings which sorts by day of week first
// => [ 2020-12-14T18:12:07.000Z, 2020-12-13T18:12:07.000Z ]

dates[sort](); // compares using natural order of dates
// => [ 2020-12-13T18:12:07.000Z, 2020-12-14T18:12:07.000Z ]
