Why .parentNode is underfined?

<div class="question"> 
 <form class="delete-form" type="POST">
 <a class="btn btn-danger delete-btn" data-pk="{{ question.pk }}">Delete</a>

$('.delete-btn').click(function(e) {
 let btn = $(this);

 type: 'POST',
 url: 'some_url',
 data: {
 // Some data
 success: function(data) {
 // Remove question
 btn.parentNode.removeChild(btn) // HERE PROBLEM WAS CALLED
 error: function(error) {
 // Danger

I want to remove .question (parent button)
Why is it when I write console.log(btn) displays the object buttons, when you write btn.parentNode - underfined. How to fix?

let btn = $(this);
$ - jquery,
this - HTMLElement,
$(this) object in jquery.

The object of jquery there is no property parentNode. He has method parent().
parentNode is from HTMLElement.

remove()that you suggest, here and there, but you have to understand what you are doing than to rely on a good match.
