title: How to update specific object inside the array?
body: <p>I have a data that looks like below in MongoDB</p>
  <pre><code>{
  _id: aasdfeasfeasdf,
  todo: [
           {_todoIde: 333, _with: []},
           {_todoIde: 111, _with: []},
        ]
  }
  </code></pre>
  <p>I want to <code>$addToSet</code> value to <code>_todoIde: 333</code>'s <code>_with</code> like <code>{_todoIde: 333, _with: [aaaa]},</code>. How can I do it?</p>
  <pre><code>.updateOne(
     {_id},
     { $addToSet: {}}
  )
  </code></pre>
  <p>I got to the document but I can't specify that <code>_todoIde: 333</code> to update just that one.</p>
