How to find from elements with one to multiple class names just the ones which feature exactly a specific and sole class name (and not any other)?

Example:

<div class="parent">
<div class ="parent father">

const soleParentClassElementList = document.querySelectorAll('.parent')

With the above code line I would query both element nodes, but I want to query just the one(s) with a single parent class.

>Solution :

this way…

const onlyParent = document.querySelector('[class="parent"]')


onlyParent.textContent = 'this one'

<div class ="parent father">...</div>

<div class="parent"> ... </div>
