JSON

Given a string of JSON data, how can you safely turn that string into a JavaScript object?

Obviously you can do this unsafely with something like...

var obj = eval("(" + json + ')');

...but that leaves us vulnerable to the json string containing other code, which it seems very dangerous to simply eval.
