Is there a method to clone an array in jQuery?

Question

This is my code :

var a=[1,2,3] b=$.clone(a) alert(b) 

Doesn't jQuery have a 'clone' method? How can I clone an array using jQuery?

Answer 1

Just use Array.prototype.slice.

a = [1]; b = a.slice();

Answer 2

What about the jQuery.merge ?

copy = $.merge([], a);
