I'm looking for a good algorithm to get all the elements in one array that are not elements in another array. So given these arrays:

var x = [a,b,c,t];

var ​​​​​​​​​y = [​​​​​​​d,a,t,e,g];

I want to end up with this array:

var z = [d,e,g];

I'm using jquery, so I can take advantage of $.each() and $.inArray(). Here's the solution I've come up with, but it seems like there should be a better way.

// goal is to get rid of values in y if they exist in x

var x = [a,b,c,t];

var y = [d,a,t,e,g];



var z = [];

$.each(y, function(idx, value){

  if ($.inArray(value,x) == -1) {

    z.push(value);

  }

});

​alert(z);  // should be [d,e,g]

Here is the code in action. Any ideas?
