In this chapter, we learned about what Node.js is and how its single-threaded, asynchronous, event-driven programming model can be used to build simple and efficient applications. We also learned about nvm and how to manage multiple versions of Node.js. Then, we studied npm and used external libraries in our Node.js applications. Finally, we learned what npm scripts are and some basic concepts related to them.
To help you understand what you learned about in this chapter, you can go to the npm repository, find some projects, and explore their code bases. The best way to learn about npm, Node.js, and the packages and libraries that exist out there is to explore other people's code and see what and how they are building and also what libraries they use.
In the next chapter, we will explore the Node.js APIs and learn how to use them to build a real web scraping application. In future chapters, you will learn how to use npm scripts and packages to improve the quality...
