Overview of this book

Functional programming is a powerful programming paradigm that can help you to write better code. However, learning functional programming can be complicated, and the existing literature is often too complex for beginners. This book is an approachable introduction to functional programming and reactive programming with TypeScript for readers without previous experience in functional programming with JavaScript, TypeScript , or any other programming language. The book will help you understand the pros, cons, and core principles of functional programming in TypeScript. It will explain higher order functions, referential transparency, functional composition, and monads with the help of effective code examples. Using TypeScript as a functional programming language, you’ll also be able to brush up on your knowledge of applying functional programming techniques, including currying, laziness, and immutability, to real-world scenarios. By the end of this book, you will be confident when it comes to using core functional and reactive programming techniques to help you build effective applications with TypeScript.

Functional Programming Techniques

After learning how to work with functions in detail, mastering asynchronous programming, and going through the main characteristics of the JavaScript runtime, we are now fully ready to focus on functional programming. In this chapter, we are going to focus on the most fundamental functional programming techniques and patterns.

We are going to try to avoid using external libraries and we are going to implement some of these techniques and patterns from scratch. This will be slightly more tedious, but it will help us to fully understand how these techniques work internally. Please note that some of these implementations have been simplified and do not cover all the potential edge cases. In an actual production system, using a well-tested functional programming library is recommended.

In this chapter, we are going to learn about the following functional...
