So I have a word of caution. As someone else in the thread mentioned, React is very intuitive for beginners. There's another framework I've used that was also intuitive for beginners: Backbone. The reason why Backbone is inferior to Angular and Ember is because it optimized for the beginner. Angular and Ember are optimized for the experienced developer on a large code base.

Specific to your suggestion, which I think is awesome, is the idea of composibility. The easiest kind of component to write is a large component with lots of options, like jQuery plugins. This is the hardest kind of component to use outside of its intended use case.

What makes Angular so good is that the core directives are all extremely composable. They can be used all over the place without hacking.

To make your dream come true we as component authors must design carefully to make smaller, more focused tools, rather than large components, because large components are harder to adapt to applications outside their main use case.
