In this chapter, we are going to make some applications. We are going to discover how JavaScript programs can work with functions to control how data is processed and then move on to consider how JavaScript applications can fetch services from the Internet. Finally, we’ll use the Node.js platform to create a JavaScript-powered web server of our own and build an application that can consume services from it. At the end of this chapter, you will know how web applications really work and how to build one of your own.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
