Filtering JavaScript Arrays

Below is an example of how you can filter a JavaScript array using jQuery

var foo = new Array(5);
foo[0] = "zero";
foo[1] = "one";
foo[2] = "two";
foo[3] = "three";
foo[4] = "four";

alert(foo);

fooSelected = jQuery.grep(foo, function(value) {
        return value != "three";
} );

alert(fooSelected);
