I have array [1, 2, 3, 4, 10, 11, 12, 20, 29, 30, 39, 40, 49, 101, 110, 119, 123]

I want to sort by keeping first digit e.g

1
10
101
11
110
119
12
123
2
20
29
3
30
39
4
40
49

is there a correct name for this sort? tried text and different methods unsure how to do this

CodePudding user response：

.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()
);
