title: Sort descending by multiple keys in jq
body: <p>I have the following array:</p>
  
  <pre><code>[{
      "name": "Object 1",
      "prop1": 5,
      "prop2": 2
  }, {
      "name": "Object 2",
      "prop1": 6,
      "prop2": 4
  }, {
      "name": "Object 3",
      "prop1": 5,
      "prop2": 3
  }]
  </code></pre>
  
  <p>I want to sort this array analogous to this SQL <code>ORDER BY prop1 DESC, prop2 ASC</code> so I have this result:</p>
  
  <pre><code>[{
      "name": "Object 2",
      "prop1": 6,
      "prop2": 4
  }, {
      "name": "Object 1",
      "prop1": 5,
      "prop2": 2
  }, {
      "name": "Object 3",
      "prop1": 5,
      "prop2": 3
  }]
  </code></pre>
  
  <p>How can I sort an array a) descending by a key and b) by multiple keys?</p>
  
  <p>Version: jq 1.5</p>
