Firestore - Delete a field inside an object : <p>I'm using Firestore and I would like to delete a field that is in a specific object.
I can delete a field in a document thanks to : </p>

<pre><code>fieldName: firebase.firestore.FieldValue.delete()
</code></pre>

<p>But if I have an object like : </p>

<pre><code>songList {
songName1: "HelloWorld",
songName2: "AnotherSong",
songName3: "andTheLastOne"
}
</code></pre>

<p>In order to delete the field songName3, I won't be able to do something like : </p>

<pre><code>songList.songName3: firebase.firestore.FieldValue.delete()
</code></pre>

<p>Is there a way to delete a field inside an object ? Or should I delete the whole object, rebuild it without the 3rd field and save it ?</p>

<p>Thanks in advance,</p>
