Firebase How to update multiple children?
<p>I have parent with many children like this:</p>

<pre><code> Parent:{
        "childe1":"data",
        "childe2":"data",
        "childe3":"data",
        "childe4":"data",
        "childe5":"data"
 }
</code></pre>

<p>How can I update the children <code>[ childe1 , childe2 , childe3 ]</code> at same time, preventing any other user from updating them at same time?</p>
