In this chapter, we looked at how to protect our components from faulty properties. We also saw how easy it was to use cookies, although they are limited for what we need. Fortunately, we can use local storage and work it into our existing backend and components.
Finally, we explored using events to push state changes out to all interested components.
In the next chapter, we will start prettying up our components. We'll look at ways to style and animate them, bringing our interface to life!
