title: How can I implement a .forEach native using a lodash _.forEach?
body: <p>I have the following:</p>
  
  <pre><code>var new = {};
  old.forEach(function (u) { new[u.id] = u.name; });
  </code></pre>
  
  <p>Can someone explain to me how I can implement this using the _.forEach that comes with lodash.</p>
