In this chapter, we introduced a practical CDK starter project you can use when coding CDK. We also learned about some core CDK concepts such as apps, stacks, and constructs. Finally, we created a custom construct and used it in our stack.
In the next chapter, we will take this example further and create a web application that exposes a RESTful API. We will also finally look deeper into the CDK and AWS CloudFormation relationship and how understanding CloudFormation templates will help you when developing CDK applications.
