Edit Question
Title
Body
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?
