How to deep copy an object in javascript as object not as array

var x = {attr1: "value", attr2: "value"};
var y = $.extend(true, [], x);
var z = $.extend(true, [], x);

alert($.type(x)); // object
alert($.type(y)); // array [ why not object too ]
alert($.type(z)); // array [ why not object too ]

To make a deep copy of an object in javascript is to do JSON.parse(JSON.stringify(obj)). In the context of your question, this could be done as follows:

var x = {attr1: "value", attr2: "value"};
var deep_copy = JSON.parse(JSON.stringify(x));

Instead of 

var y = $.extend(true, [], x);

Try 

var y = $.extend(true, {}, x);
