Question

I want to clone an object in Javascript. I have:

 iPath = function () { this.heading = 0; this.path = []; };
 loop = new iPath();

I know with jQuery I can do something like:

 cloneLoop = $.extend(true, {}, loop);

but than

 assert(cloneLoop instanceof iPath, "fails because loop is not an iPath");

How can i do a deep clone fulfilling last assert statement?

How about this:

cloneLoop = $.extend(true, new iPath(), loop);

…though I’m not sure if you’d want to do a deep copy. I’d think this would be better:

cloneLoop = $.extend(new iPath(), loop);
