title: Is mongoose.Types.ObjectId() an absolutely Node.js client-side operation?
body: <p>I'm using the Mongoose next to the Node.js. The question is:</p>
  
  <p>Does the following command for creation of the ObjectID value make a call to the server?</p>
  
  <pre><code>mongoose.Types.ObjectId()
  </code></pre>
  
  <p>I've checked my local MongoDB server log, and it doesn't show anything like a call to the single local MongoDB node/server for requesting a new ObjectID value. However, I'm not sure if the default server log is about all the operations(trivial and essential ops), or not!</p>
  
  <p>NOTE: trivial ops here means the non-manipulative data operations!</p>
