React is a UI component framework. The testing-in-isolation and composition you can do with React makes it very productive. It's good for reasoning about the fine details in a UI.

Yeah, it would be good to get a router and couple that with React. React is not a total solution for making a web app, and anyone that picks it up seriously will learn that very quickly.

We need lots more libraries like React that focus on one area of development and do that well rather than all these own-the-world frameworks that have both shiny and awkward parts. I want devs to do their front-end library selections very carefully and build a mosaic that fits together well for their app's particular use cases.
