To get the keys from nested objects, you first need to put your code in a function, then for each of the top-level keys, check if it's an array or object. If it is, just call your function again from within that function (weird, I know.) Just make sure you don't skip the check of whether it's an object. You'll get stuck in an infinite loop. Something like this:

function parseObjectKeys(obj) {
  for (var prop in obj) {
    console.log(prop)
    var sub = obj[prop]
    if (typeof(sub) == "object") {
      parseObjectKeys(sub);
    }
  }
}
