You're not comparing Python to Java, where the verbosity differences are intrinsic to the languages. Programming in the large definitely requires different techniques that can bloat small code examples, but shrink larger code bases. Consider the example of a system that communicates with a server and modifies the layout based on signals and the data the server returns. Backbone can simplify your code by abstracting away some of the details of transferring the data into the rendering code.
