In this chapter, you learned about setting up a development environment for writing serverless applications by installing Visual Studio Code, and gained an understanding of the Node.js programming language, and installed it. You also learned about Postman and how it can help you to API test serverless applications. You also learned about the different Node.js SDKs that AWS, Microsoft Azure, and GCP provide, which we will be using in later chapters to write our serverless applications.
In the next chapter, we will dig deep into what AWS Lambda is and other serverless offerings from AWS.
