Summary

In this chapter, you learned even more about ES6 classes and how they complement React components in structure and functionality. We also looked at some interesting uses of state and properties.

Above all, we saw how it's both possible and beneficial to avoid the internal component state. Properties are a powerful tool for component design. We know how to react to changing properties and how to reduce the work React needs to do to render our interfaces.

In the next chapter, we are going to discuss how to persist this data (to different kinds of local storage). We will see how to connect to these data stores through events.
