Don't worry about how anything compares to frameworks, because they don't matter anymore.

We think traditional frontend frameworks - whether of the rails/django variety or the backbone variety, are generally rubbish in a nearly infinite number of ways. It's a style of programming based on wrapping weak mutation oriented idioms behind monolithic APIs and design patterns. We think default functional style and fine grained composability is the future, and mutation + oo design patterns + frameworks is the past.
