Master functional programming techniques with this comprehensive guide for writing cleaner, safer, and performant JavaScript code Functional programming is a programming paradigm for developing software using functions. With functional programming, you can write more concise code, with increased concurrency and performance. Moreover, the JavaScript language is particularly compatible with functional programming. In this book, you'll explore major topics in functional programming with JavaScript to effectively produce shorter, cleaner, and testable programs. You'll delve into functional programming, and get up to speed with writing and testing pure functions, and even reducing side-effects, along with discovering other features to make your applications functional in nature. As you advance, you'll cover techniques to simplify coding, apply recursion for loopless coding, achieve immutability, implement design patterns, and also work with data types. By the end of this book, you'll have mastered the JavaScript skills you need to confidently program functional applications. If you are a JavaScript developer who wants to apply functional programming techniques, then this book is for you. Basic knowledge of functional programming concepts is required.
