title: JSON Parse Error on line 1 column 1
body: <p>I am getting:
  <code>SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data</code>
  when trying to parse an input string.</p>
  
  <p>The input string is as follows:</p>
  
  <pre><code>{
      "data": [{
              "id": "1124647450995962",
              "name": "Softex HelloKity Jr.",
              "picture": {
                  "data": {
                      "height": 256,
                      "is_silhouette": false,
                      "url": "https:\/\/scontent.xx.fbcdn.net\/v\/t1.0-1\/c25.0.256.256\/10407468_575157839278262_6777986632930149130_n.jpg?oh=d18d635599e2c5b2175cd03765c96a8e&amp;oe=5970D616",
                      "width": 256
                  }
              }
          },
          ...
      ],
      "paging": {
          "next": "https:\/\/..."
      }
  }
  </code></pre>
  
  <p>I cannot understand why I get an error on line 1 column 1. It seems to work fine with the following data:</p>
  
  <pre><code>var x = '{ "a" : [ 1,2,3] }';
  var d = JSON.parse(x);
  document.write(d.a);
  </code></pre>
