Summary
At the beginning of this chapter, it was stated that Node.js programming can be tough because of its asynchronous nature, especially for people used to developing on other platforms. However, throughout this chapter, you saw how asynchronous APIs can be bent to your will. You discovered that the tools at your disposal are indeed versatile and provide good solutions to most of your problems, in addition to offering a programming style for every taste.
In this chapter, we also kept refactoring and improving our web crawler example. When dealing with asynchronous code, it can sometimes be challenging to figure out the right ergonomics that can keep your code simple and effective, so allow yourself some time to digest the concepts explored in this chapter and to experiment with them.
Our journey with asynchronous Node.js programming has just started. In the next few chapters, you will be introduced to other broadly adopted techniques that leverage promises, and async/await...
