Often while writing complex programs, developers end up in situations that don't seem to work according to the logic they conceived while writing that piece of code at first. This is when debugging comes into the picture, trying to break the complex logic into smaller functionalities and then understand individual pieces.
In this chapter, we learned about debugging operators and then covered testing asynchronous code. Since you will be writing a lot of networking code for your real-world applications, this chapter laid down the foundation for making your networking code more robust.
