how to get total min and max from 2 array

Question

I have 2 Arrays:

var ids = new Array(1234,4113,1111,1111,1234,1234);
var datas = new Array(2,4,5,1,2,8);

I want to get total min. & max. values from datas array but it must be filtered, so same id can not be counted.

//example result: 
var min = 2 * 4 * 1;
//example result: 
var max = 8 * 4 * 2;

Any ideas?

Thanks!

John Resig (of jQuery) has suggested a great set of methods for this ( blog post ):

Array.max = function( array ){
  return Math.max.apply( Math, array );
};

Array.min = function( array ){
  return Math.min.apply( Math, array );
};
