## Description
<section id='description'>
In the good old days this was what you needed to do if you wanted to edit a document and be able to use it somehow e.g. sending it back in a server response. Mongoose has a dedicated updating method : <code>Model.update()</code>. It is bound to the low-level mongo driver. It can bulk edit many documents matching certain criteria, but it doesn’t send back the updated document, only a ‘status’ message. Furthermore it makes model validations difficult, because it just directly calls the mongo driver.

## Instructions
<section id='instructions'>
Find a person by <code>_id</code> ( use any of the above methods ) with the parameter <code>personId</code> as search key. Add &quot;hamburger&quot; to the list of the person&apos;s <code>favoriteFoods</code> (you can use <code>Array.push()</code>). Then - inside the find callback - <code>save()</code> the updated <code>Person</code>.
<strong>Note:</strong> This may be tricky, if in your Schema, you declared <code>favoriteFoods</code> as an Array, without specifying the type (i.e. <code>[String]</code>). In that <code>casefavoriteFoods</code> defaults to Mixed type, and you have to manually mark it as edited using <code>document.markModified('edited-field')</code>. See Mongoose documentation at https://mongoosejs.com/docs/schematypes.html#Mixed
