In this chapter, we have built a small module that allowed us to get a greater insight into Magento's customerData and sections mechanisms. We managed to build a single component, that got used both on the customer's My Account page, as well as on the checkout.
With this, we have reached the end of our book. The topics we have covered should be enough to get us going with Magento development, but the sheer size of the platform and the intricate specifics of its individual modules leave plenty more to explore further on. It goes without saying that our journey has merely begun.
