A convenient and easy-to-use framework that allows one to easily release single-page applications in the shortest possible time — all this is Backbone. Along with it, other extra tools are used, for example, Marionette, Chaplin, Thorax. When developing apps to be applied by a variety of user groups, one needs a convenient classification tool, and the Backbone’s subsections of arrays and collections are suitable for separating parts. When using models, collections, views, and routes, one can take advantage of this framework’s events.
