Hi. What do you think, in what order will the numbers be and why?

Question

const arr = [ 2, 13, 26, 8, 10];
arr.sort();
console.log(arr);

Answer 1

The sort() method takes an additional optional argument, which is the compare function.

If the compare function is not provided, then all the numbers are converted to strings and are sorted lexicographically.

So we need to provide the compare function to sort the numbers.
const arr = [ 2, 13, 26, 8, 10];
arr.sort(function(a, b) { return a - b; });
console.log(arr);

Answer 2

It appears that the array elements were treated as string instead of number. The elements ordering seems to be performed lexicographically.

But I can't answer the "why" part (sorry)
