[Solved] sorting by first digit


.sort() should reorder the items like that by default.

The default sort order is ascending, built upon converting the elements into strings, then comparing their sequences of UTF-16 code units values.

console.log(
  [1, 2, 3, 4, 10, 11, 12, 20, 29, 30, 39, 40, 49, 101, 110, 119, 123].sort()
);
