title: Underscore - Find from a sorted array of objects
body: <p>Underscore provides the function <code>sortBy</code> to sort an array of objects. However once I have this sorted array, is there a way to find an element using binary search? The function <code>find</code> does not leverage the fact that the array is sorted, while the function <code>indexOf</code> does, but it does not provide a way to specify the sort key.</p>

  <li>Is there any other JS library that allows to do this easily?</li>
