In Drupal development, understanding the differences between hooks and event subscribers is essential for building robust and flexible modules. Hooks are a fundamental part of Drupal's architecture, allowing modules to interact with and modify various aspects of the system's behavior. Moreover, event subscribers are a more recent addition to Drupal, introduced in Drupal 8 as part of its transition to a more modern, object-oriented architecture.
