title: how to calculate length of JSON array using JMeter?
body: <p>I am using Jmeter to make an API call. The response is:</p>
  
  <pre><code>{
    "qid": [
      {
        "id": "88e4b027b72f793d3c",
        "created": 1410955125065
      },
      {
        "id": "54197788e4",
        "created": 1410955125065
      },
      {
        "id": "788e4",
        "created": 1410955125065
      },
      {
        "id": "5419778",
        "created": 1410955125065
      },
      ....
    ]
  }
  </code></pre>
  
  <p>The length of the JSON array varies for different API requests. How do I determine the length of the JSON array?</p>
