      <p>Deprecating code is a way of identifying code that will be removed in a future major version.</p>

      <p>For example, the <code>drupal_set_message()</code> function was deprecated in Drupal 8.5 and removed in Drupal 9 as the <code>messenger</code> service replaced it.</p>

      <p>Once it was deprecated, the function was changed to use the new service to avoid duplicating code and a message was added to notify Developers:</p>

      <pre><code class="language-php">function drupal_set_message($message = NULL, $type = 'status', $repeat = FALSE) {
        @trigger_error('drupal_set_message() is deprecated in Drupal 8.5.0 and will be removed before Drupal 9.0.0. Use \Drupal\Core\Messenger\MessengerInterface::addMessage() instead. See https://www.drupal.org/node/2774931', E_USER_DEPRECATED);

        $messenger = \Drupal::messenger();
        if (isset($message)) {
          $messenger-&gt;addMessage($message, $type, $repeat);
        }

        return $messenger-&gt;all();
      }
      </code></pre>

      <p>This approach means that code can be refactored without breaking backwards-compatibility and, to upgrade any custom code to be compatible with Drupal 9, any references to <code>drupal_set_message()</code> just needed to be updated to use the new Messenger service.</p>

      <p>No large rewrite needed!</p>
