This chapter was an amazing journey from start to finish, and it has taught us from the very beginning about Node.js. We didn't opt for explaining stuff in computer science terminology, instead we went to the mechanical part of the V8 engine, and from there we saw how real-world objects can be mapped into computing.

We learned what Node.js is, from where this most amazing library started, who built it, and why and how it's helping us create real-time web apps.

Then we moved to Q, the best way to offer promises to Node.js. We saw how we can install Q and then we saw different ways of using Q along with Node.js. We have also achieved our purpose of using Q as a promises implementation of Node.js.

This chapter will encourage you to start working on Node.js, especially on how to take advantage of Q as the library of promises for Node.js.

In the next chapter, we will be looking in-depth in the world of Angular.js and how it got promises implementation.
