In this chapter, we learned about Node and Express. Node is the core server-side technology that drives a huge percentage of servers on the web, and Express is the most popular and often used Node-based framework for building web applications. We now have a complete picture of how frontend and backend technologies work to create websites.
In the next chapter, we'll learn about GraphQL, an extremely popular and relatively new standard for creating web-based API services. Once we've covered this, we will have all the knowledge we need to start building our project.
