title: Getting an object from _.pluck with lo-dash/underscore
body: <p>I have an object structured like this:</p>
  
  <pre><code>var my_object = {
    first_item: {important_number: 4},
    second_item: {important_number: 6},
  }
  </code></pre>
  
  <p>However, I would like an object structured like this:</p>
  
  <pre><code>{
    first_item: 4,
    second_item: 6,
  }
  </code></pre>
  
  <p>I would have expected to be able to get this result with <code>_.pluck</code>:</p>
  
  <pre><code>_.pluck(my_object, "important_number")
  </code></pre>
  
  <p>But this gives me:</p>
  
  <pre><code>[0: 4, 1: 6]
  </code></pre>
  
  <p>Good, but I need the actual names of the objects. I fiddled around and ended up with this:</p>
  
  <pre><code>_.reduce(my_object, function(memo, val, key) {
    memo[key] = val.content;
    return memo;
  }, {});
  </code></pre>
  
  <p>Which has the desired effect, but isn't as simple as I would like. Is there a better solution in underscore/lodash, or is this the best it will get?</p>
