Functional programming is very fun for rapid prototyping and designing new ideas. But it is also difficult to study if you are new to the field.

Devs with knowledge of procedural programming will have an easier time to start, but once you move can be very fun. Haskell is one of the most interesting functional languages and if you have the temerity to learn that I guarantee you will enjoy what Haskell can offer. You can hire freelancers from the freelance gigs posted by them to help you.

But where to start? Well, in this post, I seven best-sketched books to study Haskell’s first step. This collection includes books for beginners, developers and intermediate programmers more advanced to ideally meet the needs of all.

  1. Real World Haskell

This can be the ultimate guide to learning Haskell if I saw one. First published in 2008, this book still holds today with more than 700 pages of introductory tutorials and guides for beginners.

Real World Haskell takes you to the step of functional programming step by step with real exercises to guide you along the way. But you do not just learn how to write Haskell code; You will learn how to think like a programmer working on ways to build Haskell applications.

You can take this as a novice to Haskell and always walk with solid knowledge. However, you need some general understanding of programming concepts such as variables, functions, and classes.

As this book is a huge one you will learn a little bit about everything from coding and networking development of regular web/desktop application expressions. This is easily one of the best introductory guides to Haskell with a no-frills approach to teaching. Hire freelancers to help you guide you through as well.

  1. Learn Haskell for a great good!

Perhaps the funniest book market programs, this is one of the best intros in Haskell you will find. The intelligent use of the author’s illustrations and humor gag make for an enjoyable reading. The style of writing is very affordable and Haskell concepts are introduced in a playful and educational spirit.

Find out you’re Haskell’s greatest good! It starts with the absolute basics of Haskell and moves you through each prominent feature. You will eventually learn how to create their own programs from scratch with the types of classes and modules.

Some knowledge of imperative/procedural programming will help you through this book much faster. You can work with examples without any programming knowledge, although it will take you a lot longer than others.

I am a big fan of this book with playful nature, amazing illustrations and humorous pop culture dialogue accompanied by the witty joke. The book covers 360 pages and actually makes Haskell somehow learn a fun adventure.

  1. Haskell: The Functional Programming Profession

Functional programming is not an easy subject to grasp. And starting with Haskell can be even more complex unless of course, you have the right study material.

Haskell: The business of functional programming is a collection of 600 pages currently in its 3rd edition. I think this is one of the best primers in functional programming you walk through the absolute basics in more advanced subjects.

It can take months or even years to understand Haskell. It has many applications but requires rigorous tenacity to cross. That’s why I love this book specifically for its value in teaching functional programming starting with the basics. Most freelance post it as freelance gigs.

You can get this book without prior knowledge and do it through well. But remember it will take hours of dedicated practice and the most challenging parts can be incredibly frustrating.

  1. Beginning Haskell: A Project-Oriented Approach

The study is based on work a project allows you to see how Haskell behaves in the real world. From Haskell: An approach based on innovative Haskell projects in a step-by-step learning process that make perfect sense.

You will still learn all theoretical concepts such as arrows and monoids. But you learn the pragmatically. You can get this book with zero experience Haskell and always walk with a good understanding of functional programming.

The three main OS environments are covered and you can use an IDE of your choice. The author assumes some familiarity with general programming concepts, but it is highly unlikely that anyone has Haskell as their first language.

Though This book goes fast, it is also very comprehensive. I highly recommend to anyone who has some knowledge of functional programming or procedure and is willing to learn Haskell from a practical plan by the project.

  1. Thinking with Haskell Functionally

Think Functionally Haskell is another book that initiates students eager for functional programming in the world of Haskell. You will learn to write functional code in the right path, focusing on mathematical models.

With more than 100 different exercises, you will be able to learn all the finest points of development Haskell. You get to build a pure Sudoku puzzle solver and an equational calculator from scratch.

Practical examples go a long way to ingraining best practices into their workflow. This manual has been made for undergraduate students, but can be studied by anyone who is willing to sit down and go into town with Haskell.

  1. Web application development with Haskell and Yesod

When you think about developing web applications, you rarely think about Haskell. But with the Yesod framework can create RESTful Haskell web apps from scratch.

If you are willing to try Haskell web then consider picking up a copy of the web application development with Haskell and Yesod: Web Development Security-Driven.

With this book, you will learn how to set up a new Yesod environment, create forms, and how to properly handle incoming content management of the RESTful API. Practical exercises require you to consider Haskell a real world perspective, creating a blog application and Sphinx search server.

The products you create with Yesod / Haskell will be unique for web development. This may not be the most popular choice for a web structure, but it is fun to play with and see what you can build.

  1. Haskell Design Standards

Development and design templates are a great reason why many developers come together in functional languages like Haskell. You can accomplish so much and workflow can be studied and consistently applied in many design models domínios. Haskell takes you step beyond functional logic to help you understand how to best design your Haskell projects. This is an advanced book covers various development techniques such as Haskell Imperative, Lazy and Iteratee for I / O Channels

This book also covers the type system in detail explaining what makes the Haskell different from other programming languages.

If you are a beginner, I recommend another beginner book (almost anything will do). Once you know a little more about Haskell you can move around in this book to learn more about best practices for quality code writing.

Haskell is not an easy language to pick up. Some of the basics can be learned in a day, but to build anything with Haskell you need to put in weeks or months.

These seven best books will take you where you need to go and all can be useful for developers of different skill levels. For beginners, I recommend the real world Haskell for its length and clear writing style.

Once you pass this step, you can pretty much nowhere. You can focus on visualizing data, web applications with Yessod or functional programming with high-level multi-threaded applications.
