This is the code repository for Hands-On Functional Programming with Typescript, published by Packt.

Explore functional and reactive programming to create robust and testable TypeScript applications

Functional programming is is a very powerful programming paradigm that can help us to write better code. However, learning functional programming is complicated and the existing literature is often too complex for beginners.This book is a 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.

This book covers the following exciting features: The pros and cons of functional programming while compared against object oriented and imperative programming Build real-world functional-reactive web applications with React + MobX and Cycle.js Principles, patterns and best practices of reactive programming such as observers, observables and event streams How to use Lazy.js to help improve the performance of our applications The working of functional optics with monocle-ts The category theory functional data structures such as the Maybe, Just and Monad
Use functions as values so we can pass them as arguments to other functions

greetUnnamed = function(name: string): string {
    return 'Hi! ${name}';
};

Following is what you need for this book: This book is designed for readers with no prior experience of functional programming with JavaScript, TypeScript or any other programming language. Some familiarity with TypeScript and web development is a must to grasp the concepts in the book easily.
