/**

* The sort() method sorts the elements of an array in place and returns the sorted array.

* The default sort order is ascending, built upon converting the elements into strings,

* then comparing their sequences of UTF-16 code units values.

*

* Internally uses Three-way-comparission (a<b => -1, a>b => 1, a=b => 0)

* https://en.wikipedia.org/wiki/Three-way_comparison
