This is going to be the best option for you.

app/code/Vendor/Wishlist/etc/di.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <type name="Magento\Wishlist\CustomerData\Wishlist">
 <plugin disabled="false" name="Vendor_Wishlist_Plugin_Magento_Wishlist_CustomerData_Wishlist" sortOrder="10" type="Vendor\Wishlist\Plugin\Magento\Wishlist\CustomerData\Wishlist"/>
 </type>
</config>

app/Vendor/Wishlist/Plugin/Magento/Wishlist/CustomerData/Wishlist

 <?php
/**

declare(strict_types=1);
namespace Vendor\Wishlist\Plugin\Magento\Wishlist\CustomerData;
class Wishlist
{
 protected $wishlistHelper;
 public function __construct(
 \Magento\Wishlist\Helper\Data $wishlistHelper
 )
 {
 $this->wishlistHelper = $wishlistHelper;
 }
 public function afterGetSectionData(
 \Magento\Wishlist\CustomerData\Wishlist $subject,
 $result
 ) {
 // Your code here
 return $result;
 }
}

• zus: I am getting an error when i try to add the function: snipboard.io/XOK5Av.jpg inside the module.
• zus: I am trying to add the wholee function what i edit inside the C:\xampp\htdocs\m3\vendor\magento\module-wishlist\CustomerData\Wishlist.php
• Dava Gordon: Well you don't add it inside a function you would add it after the afterGetSectionData function
• Dava Gordon: Also you cannot overwrite a protected function you would need to do you modifications in the afterGetSectionData function
• zus: I am getting confused, 1) should i add the function which i edit in the core wishlist.php after the afterGetSectionData right? ( code : codeshare.io/anxjMV )
