Summary

In this chapter, we went through the most common programming paradigms in Node.js. We learned how Node.js handles parallel requests. We understood how to write modules and make them communicative. We saw the problems of the asynchronous code and their most popular solutions. At the end of the chapter, we talked about how to construct our application. With all this as a basis, we can start thinking about better programs. Software writing is not an easy task and requires strong knowledge and experience. The experience usually comes after years of coding; however, knowledge is something that we can get instantly. Node.js is a young technology; nonetheless, we are able to apply paradigms and concepts from client-side JavaScript and even other languages.

In the next chapter, we will see how to use one of the most popular frameworks for Node.js, that is, Express.js, and we will build a simple website.
