Becoming Functional - Several Questions

–Functional Programming (or FP, as it's usually shortened) has been around since the earliest times and is going through a sort of revival, due to its increased use with several frameworks and libraries, and most particularly in JavaScript. In this chapter, we shall:

• Introduce some concepts of FP, to give a small taste of what it means

• Show benefits (and problems) implied by the usage of FP

• Start thinking about why JavaScript (JS) can be considered to be an appropriate language for FP

• Go over the language features and tools that you should be aware of, to fully take advantage of everything in this book

So, let's get started by asking ourselves What is FP? and start working on that topic.
