Summary

We've learned a lot in this chapter, specifically:

• That JavaScript has a life outside web browsers

• The difference between asynchronous and blocking I/O

• The attributes of Node, and where it fits in the overall web application platform market

• Threaded versus asynchronous software

• The advantages of fast event-driven asynchronous I/O, coupled with a language with great support for anonymous closures

• Node performance

Now that we've had this introduction to Node, we're ready to dive in and start using it. In Chapter 2, Setting up Node, we'll go over setting up a Node environment, so let's get started.
