The main benefit associated with the Angular framework is the ease of use for developers experienced in Java and object-oriented programming. In addition, Google offers excellent user support when developers encounter problems. Two of the main challenges associated with the Angular framework are the steep learning curve and the fact that many novice developers struggle with TypeScript if they do not have a background in Java or C#.
One of the main advantages of Backbone is the stability of the framework. The author, Jeremy Ashkenas, has refused to release updates to the framework since 2010. While the lack of updates has prevented this framework from integrating new ideas and features, it provides the web development approach with some much-needed stability. However, the static nature of this framework also means that Backbone has steadily lost ground to new, more-efficient frameworks that have been created in the past several years.
