this is my html file

<script>

var output = console.dir(location);
document.write(output);

</script>

and iam trying to assign console output to a variable "output"
but its output is just

undefined

what i need is somewhat like,

{
  "ancestorOrigins": {
    "0": "https://www.google.com"
  },
  "href": "about:blank",
  "origin": "null",
  "protocol": "about:",
  "host": "",
  "hostname": "",
  "port": "",
  "pathname": "blank",
  "search": "",
  "hash": ""
}

output would be a json or array but it wouldn't be undefined
or do i have to use try & catch or something like that to get its output
