:two_words_connector- The sign or word used to join the elements in arrays with two elements (default: “ and ”). -
:last_word_connector- The sign or word used to join the last element in arrays with three or more elements (default: “, and ”). -
:locale- Ifi18nis available, you can set a locale and use the connector options defined on the ‘support.array’ namespace in the corresponding dictionary file.
