jQuery $.extend - to extend an Array

Using the $.extend is working, but it returns an Object and not a native Array, so the push() won't work.
How can I extend an array, using the jQuery.extend?

var x =[1,2];
var y = $.extend({},x);
y.push(3) // fail

edit: The array WILL contain objects, so - the slice() won't do the trick

You have to give the input object as an array.

jQuery.extend(['c'], ['a','b'])

Above works as expected. Index 0 is overridden as 'a'. And index 1 is assigned 'b'. And the result is an instanceof Array.

Although, many inbuilt methods are getting added as properties on the resultant array, which might get in the way sometimes.

No need of jQuery at all use Array#concat method.

var x =[1,2];
var y = x.concat([3,4]);
y.push(3)
