title: mongoose array of array of strings
body: <p>I wish to have a Mongoose Schema property contain an array of array of strings, like so</p>
  
  <pre><code>[['one','two','three'],['four','five']]
  </code></pre>
  
  <p>How should I model this in my Schema? The following doesn't seem to work but it could possibly be another error...</p>
  
  <pre><code>names : [[{type: String, trim: true}]]
  </code></pre>
  
  <p>Do I have to make a seperate schema as per <a href="https://stackoverflow.com/questions/11342073/nested-arrays-in-mongoose">Nested arrays in Mongoose</a></p>
  
  <p>Thanks</p>
