Disappointed with Object-oriented Programming? Has imperative coding let you down? Don't worry, because Functional Programming is here to fix all your problems! Maybe! More realistically, it will show you new ways of thinking about code. So why not give it a go with a programming language you are probably already familiar with? Learn how to write programs the functional way with Typescript and the fp-ts library! This book was written for people who are less or not at all familiar with functional programming. It explains basic functional techniques (including monads) and demonstrates their use in practical examples and projects. In those projects you deploy to the AWS cloud, work with a REST API and store information in a database.
