Customizing javascript Array.sort() method

In Javascript, Array sort could be parametrized. You could change the behaviour of the Array.sort method by passing the comparison function to it :
var myArray=new Array(2,1,6,4,18,-1);

// Descending sort
alert(myArray.sort(function(x,y) {return y-x}));

// Ascending sort
alert(myArray.sort(function(x,y) {return x-y}));


You can setUp your own sort function for you own objects and needs...
