Hey Awais Bajwa,
There are a lot of new things going on in Node.js, but unfortunately this book will not teach you all of these things. However, it'll teach you a few things about cool new things in applications infrastructure and architecture! As you can guess, it's that serverless thing
We used Node.js as a language for all of our examples, but you can use basically any programming language to write your serverless application, and the concepts will be the same.
Why serverless? The idea is simple: it is an evolution of the cloud, you focus on your application business logic, and your vendor manage the infrastructure. You get auto-scaling, auto-failover, full isolation, and many other things out-of-the-box. And you pay for used capacity, not for reserved capacity. For example, our product,
Vacation Tracker, infrastructure costs $0.17 for March for more than 160 teams using the product (and most of them are paying for it). You can read more about it in the free first chapter of our book here:

Cheers,
Slobodan
