The Node.js Platform

Some principles and design patterns literally define the developer experience with the Node.js platform and its ecosystem. The most peculiar one is probably its asynchronous nature, which makes heavy use of asynchronous constructs such as callbacks and promises. In this introductory chapter, we will explore where Node.js gets its asynchronous behavior from. This is not just good-to-know theoretical information: knowing how Node.js works at its core will give you a strong foundation for understanding the reasoning behind more complex topics and patterns that we will cover later in the book.

Another important aspect that characterizes Node.js is its philosophy. Approaching Node.js is, in fact, far more than simply learning a new technology: it's also embracing a culture and a community. You will see how this greatly influences the way we design our applications and components, and the way they interact with those created by the community...
