Foundation is both feature-rich and easy to customize. React on the other hand is awesome because of its simplicity. It's even more awesome when combined with Redux and Immutable.
What's in the box?
The goal is to wrap every part of Foundation into re-usable React components following the framework's best practices. The primary focus is ease-of-use and extensibility. There are using pure render components, also known as stateless components, whenever possible to keep the memory usage to a minimum. Stateful components are only used for larger components, such as ResponsiveNavigation, where the state is actually necessary. All components are unit-tested to ensure their quality.
