title: How to iterate JSON object keys in ActionScript 3
body: <p>I'm trying to parse json in as3 that has multiple arrays like this:  </p>
  
  <pre><code>{
    "a1": [{
        "a": 1,
        "b": "2",
        "c": 3
      },
      {
        "a": 1,
        "b": "2",
        "c": 3
      }
    ],
    "a2": [{
        "a": 1,
        "b": "2",
        "c": 3
      },
      {
        "a": 1,
        "b": "2",
        "c": 3
      }
    ],
    "a3": [{
        "a": 1,
        "b": "2",
        "c": 3
      },
      {
        "a": 1,
        "b": "2",
        "c": 3
      }
    ]
  }
  </code></pre>
  
  <p>I don't really know hot to iterate through it to get the values out of each array though. I assume I'd use a for loop and append it to the end of the array name "a", but I'm not sure how to write this (if that's even the right way to approach it). </p>
