I have an json object like so:

{ 
  { 
    name: "foo"
    surname: "bar"
  },
  {
    name: "hello",
    surname: "world"
  }
}

I have two questions: What is the quickest way to convert this into an array [ {...}, {...} ]? How can I find the last object in the object list? e.g return

{
  name: "hello",
  surname: "world"
}
