Summary

In this chapter, we've explored how React and Redux can be used together to build applications beyond form-based input.

Finally, we looked at how to test-drive changing the browser's focus, rounding off our additions to the user interface.

In the next chapter, we'll look at how to test-drive something much more intricate: animation.
