Recap

Recap

In this chapter, we traveled back in time to 2009 to understand the creation of Node.js. After that, we realized why and when we should use the event-driven approach compared to a threaded model and its advantages. We came to understand what event-driven, asynchronous code is and how JavaScript helped Node.js and Deno make the most out of the server's resources.
