Description:

In Drupal 7, drupal_add_css(), drupal_add_js() and drupal_add_library() could be used to add JS and CSS to a page. In Drupal 8, these functions have been removed. Instead, you must use #attached in a render array. #attached was already available in Drupal 7, and was widely used, but now it'll be the only way to attach assets.
