sort which is default compare function

[artev]

in the default sort which is the compare function used?
alphabetical ordination is so:arry.sort();
but which is the default function used?

is there a good link wich example for alphabetical order
and also for multiarray order? (previous post)


which it is the difference between:
function compareNumbers(a, b)
{return a - b;}
and this:
function compare(a, b)
{ if (a < b by) return -1;
else if (a than b ) return 1;
else return 0;
}

No difference when used in a numeric .sort(),
as .sort() only looks for positive, zero or negative.

The first sort function should be faster,
especially important with a large array.

The second one also works in a string compare sort.

In the second function the else-es are not neccessary:

function compare(a, b) {
if (a<b) return -1;
if (a>b) return 1;
return 0;
};
