In this code, Drupal is an Object declared to be equal to itself, or, if not yet set, equal to { 'settings': {}, 'behaviors': {}, 'themes': {}, 'locale': {} } which is an Object containing 4 methods (settings, behaviors, themes, and locale) each of which is itself an Object. This line of code is an Object Initializer.
