JSON.stringify - how to use it in Symfony2

Question

Sorry for the stupid question, but I don't know a thing about JavaScript. I'm trying to use JSON.stringify to make an array looking pretty and be easy to read.

I tried this in controller:

    $metadata = '{"hello":"world", "Test":["hello"]}';
    $data = json_encode($metadata);

    return $this->render('AcmeQuotesBundle:Home:metadata.html.twig', array('data' => $data));

and this in template:

   <script>
        var obj = {{ data }}

        document.body.innerHTML = "";
        document.body.appendChild(document.createTextNode(JSON.stringify(obj, null, 4)));
    </script>

but I get a white screen.

How I can make it work?

No :( it is pointing to " in this: var obj = "{\"hello\":\"world\", \"Test\":[\"hello\"]}"; — Faery

Now I get the text, but it's on one line, I would like to print it like this jsfiddle.net/AndyE/HZPVL — Faery
