title: Extract ith item from an array in jQuery
body: <p>I need to extract the ith "age" from this array using jQuery. I'm not exactly sure how to do so, given the unique structure of my data:</p>
  
  <pre><code>[{"age":25},{"age":52},{"age":73},...,{"age":17}]
  </code></pre>
  
  <p>Any ideas?</p>
