Learning Node.js Development

The working non-blocking I/O

In our non-blocking example, this is how we'll be building our Node applications.

Let's break this code example down line by line. First up, things start much the same way as we discussed in the blocking example. We'll start the getUser function for user1, which is exactly what we did earlier:

But we're not waiting, we're simply kicking off that event. This is all part of the event loop inside Node.js, which is something we'll be exploring in detail.
