The standard sort function takes a comparison function (which "you" supply) as its argument.
As it runs, when it wants to compare two elements of the array being sorted, it calls "your" function with the elements to be compared, and uses the returned value to move the elements according to its algorithm.
The reason for doing it that way is so you can provide whatever sort order you like. for example
function(x,y){return y-x} will sort in reverse numeric order, and function(p,q){console.log(comparing p.toString() to q.toString()); return p-q} will give you a log of all the comparisons made during the sort.
If you don't specify a comparison function, it defaults to a string comparison (which is why it doesn't work with numbers).
Software rusts. Simon Stephenson, ca 1994. So does this signature. me, 2012
