I am trying to get a better understanding of the jQuery.map function.

So in general terms .map takes a array and "maps" it to another array of items.

easy example:

$.map([0,1,2], function(n){
    return n+4;
});

results in [4,5,6]

I think I understand what it does. I want to under why would someone need it. What is the practical use of this function? How are you using this in your code?
