The document discusses headless Drupal, which separates the front-end interface built with JavaScript frameworks from the Drupal backend which acts as an API. It outlines the benefits of this approach, popular JavaScript frameworks that can be used including Backbone.js and AngularJS, and how to implement headless Drupal using services and REST modules in Drupal 7 and the built-in capabilities in Drupal 8. Examples are provided and it's noted that Drupal is well positioned for the growing need for APIs and data-driven approaches to websites.
