The document discusses a journey to building a single page application using AngularJS and BreezeJS. It describes the initial solution using jQuery with problems around navigation and two-way binding. AngularJS solves these issues with routing and two-way binding. BreezeJS simplifies working with data by removing boilerplate code for model creation, queries, validation and only saving changed data. Unit testing is also enabled through Angular's dependency injection and separation of concerns. The presentation concludes that single page applications are well-suited for cross-platform mobile apps that avoid app stores, and that AngularJS and BreezeJS improve code testability and reduce data access code.
