The most efficient way to copy objects

What is the most efficient way to copy JavaScript objects? What I've seen so far is obj = eval(uneval(o)); It's like this, but it's only available on Firefox right now. obj = JSON.parse(JSON.stringify(o)); I've seen this, but my question is the most efficient way.
