Who this book is for
This book is geared toward programmers with a good working knowledge of JavaScript (or, better yet, TypeScript) working either on the client side (browsers) or the server side (Node.js), who are interested in applying techniques to be able to write better, testable, understandable, and maintainable code. Some background in computer science (including, for example, data structures) and good programming practices will also come in handy. In this book, we’ll cover FP in a practical way, though, at times, we will mention some theoretical points.
