Summary
In this chapter, we installed Node.js, saw how to interact with it from the command line, and started using it to write web applications. We learned about Express and how we can structure an application using routes and middleware.
Although we've seen some code in this chapter, we haven't really explored the JavaScript syntax in detail. Before adding more functionality to our application, we should make sure that we're up to speed with JavaScript. This is the subject of the next chapter.
