Change order of comment-form-fields

Have you reviewed https://codex.www.ads-software.com/Function_Reference/comment_form

Yes several times. But there is a lot on that page, that I don’t understand. If you or somebody could point me in the right direction, that would be great. ??

I got it working. This did the trick: https://wordpress.stackexchange.com/questions/50593/how-to-rearrange-fields-in-comment-form

Thanks for the link. I am looking for the same thing.

I changed the order of comment fields using the following code but someone on the same link has mentioned that this is not the best practice.

// comment form field order
add_filter( 'comment_form_defaults', 'remove_textarea' );
add_action( 'comment_form_top', 'add_textarea' );

function remove_textarea($defaults)
{
    $defaults['comment_field'] = '';
    return $defaults;
}

function add_textarea()
{
    echo '<p class="comment-form-comment"><textarea style="width:100%;" rows="8" id="comment" name="comment" aria-required="true" placeholder="Type your comment here..."></textarea></p>';
}

Any inputs?
