    <?php
    
    namespace Eglobe\HelloWorld\Controller\Index;
    
    class Display extends \Magento\Framework\App\Action\Action
    {
      public function __construct(
    \Magento\Framework\App\Action\Context $context)
      {
        return parent::__construct($context);
      }
    
      public function execute()
      {
        echo 'Hello World';
        exit;
      }
    }
    
    

    Step 6: Enable the module

    Open your terminal and go to magento2 root. Run the following command there:

    php bin/magento setup:upgrade

    sudo chmod -R 777 var pub/static generated

    Now open the url http://example.com/helloworld/index/display and you will see Hello World.
