Php/WebStorm is reporting this wierd warning in my JavaScript code stating that property id is not defined in the element/node. Thing is, the element is a firstChild element fetched from the parent element.

function hideChildAndUpdateID(title) 
 let parent = document.getElementById('parent');
 let child = parent.firstChild;

 // Hiding the child.
 child.style.display = 'none';
 // Temporary ID so we can find it later.
 child.id = 'child-tmp-id'; // Warning occurs here

And this is the entire message from Php/WebStorm

Property id is not defined in type Node less... (Ctrl+F1) 
Inspection info: This inspection reports assignments to undefined properties of explicitly type-annotated variables.

This code itself actually works. The child element gets it's id changed to whatever I set it to, but this warning is anoying me.

I have tried using child.setAttribute('id', 'child-tmp-id'), but that did not work properly.

Is there a convention when dealing with firstChild or it's just a Php/WebStorm thingy?

Nodes can be more than just elements and don't necessarily have an id property. Try using firstElementChild instead that returns the first child that is an element:

function hideChildAndUpdateID(title) 
 let parent = document.getElementById('parent');
 let child = parent.firstElementChild;

 // Hiding the child.
 child.style.display = 'none';
 // Temporary ID so we can find it later.
 child.id = 'child-tmp-id';

  I have in the mean time used the setAttributeNode along with createAttribute and that worked too, but this is way nicer. Thanks.
