There are some Node modules out there if don't want to "roll your own". This one looks good: https://www.npmjs.com/package/clone

Looks like it handles all kinds of stuff, including circular references. From the github page:

clone masters cloning objects, arrays, Date objects, and RegEx objects. Everything is cloned recursively, so that you can clone dates in arrays in objects, for example. [...] Circular references? Yep!
