Best Ebook Online Functional Programming in JavaScript, by Dan Mantyla

Unlock the powers of functional programming hidden within JavaScript to build smarter, cleaner, and more reliable web apps

About This Book

• Discover what functional programming is, why it's effective, and how it's used in JavaScript
• Understand and optimize JavaScript's hidden potential as a true functional language
• Explore the best coding practices for real-world applications

Who This Book Is For

If you are a JavaScript developer interested in learning functional programming, looking for the quantum leap towards mastering the JavaScript language, or just want to become a better programmer in general, then this book is ideal for you. It is aimed at programmers involved in developing reactive frontend apps, server-side apps that wrangle with reliability and concurrency, and everything in between.

What You Will Learn

• Separate core logic from the program state to write more maintainable code
• Replace ugly for loops with pure functions and recursion
• Simplify code with method chains of pure, higher-order functions
• Create more reliable code with closures and immutable data
• Explore lazy evaluation strategies and what they can accomplish
• Develop more powerful applications with currying and function composition
• Use promises, functors, monads, and function factories

In Detail

This is a fast-paced guide that will help you to write real-world applications by utilizing a wide range of functional techniques and styles.

The book first explores the core concepts of functional programming common to all functional languages, with examples of their use in JavaScript. It's followed by a comprehensive roundup of functional programming libraries for JavaScript that minimizes the burden of digging deep into JavaScript to expose a set of tools that makes functional programming not just possible but highly convenient. The book then rounds off with an overview of methods to effectively use and mix functional programming with object-oriented programming.

Highly Readable Book About JavaScript and Functional Programming By Bobby Maze This is a well-written book about JavaScript - not an easy task in my mind. The explanations of the components that make up functional programming are very clear and use simple examples. The example explaining closures made me grasp this staple functional feature more than any I had read before. I "got it", which makes me really appreciate this book and it's author. I've read other explanations, but this one clicked with me.Also, relations are pointed out between functional features that make it easy to see how some aspects of functional programming enable other aspects. For instance, pure functions enable lazy evaluation. With this explanatory approach I was able to grasp the whole and not just the individual parts. Up to this point, I've always seen functional programming as just a series of techniques without seeing the relations between these techniques and without seeing the full power and possibilities, but now I think I'm beginning to see it more holistically.The author also provides a framework for understanding functional libraries that extend javascript’s functional core. It always seemed to be confusing to me how there were so many libraries and I was always wondering which to learn and why. This framework is good for understanding not just current libraries but future libraries as well.The book is written in a clear and concise way and also with a sort of conversational tone that makes it quite readable. In other words, it doesn't bore you with what could potentially be a dry topic. I don't think programming, functional or otherwise, is boring, but from my experience, it is all too easy to write a book on a specific language or technology that ends up being a dry listing of the features of the technology with examples that have little imagination and shed little light on how to incorporate these features into a picture of the whole. This book mostly avoids falling into this trap.Overall, this book helped me to read functional code with a proficiency approaching the way I already read object-oriented code. It just came more naturally afterwards. I highly recommend this book to those trying to grasp some of the trickier parts of functional programming or for those coming from a strong object-oriented background, but without much exposure to functional programming. JavaScript ties these two paradigms together, so if you want to use it to its full effect, then you need to understand both paradigms and how they can be combined. The book helped me greatly with this understanding.The book also covers some more advanced topics, such as category theory and some pitfalls of JavaScript, and these explanations were also enlightening in deepening my understanding of functional programming and JavaScript..I think "JavaScript: the Good Parts" (a well-known book about JavaScript) is in some ways a more advanced and thorough treatment of the language (and probably for this reason, it gets a bit tedious at times). I probably should have read this book first before reading that book, as it would have made it easier to grasp. But anyway, I may now be able to go back to that book and get more out of it this time, given that I have a firmerfoundation of understanding laid down through reading this book. Also, I may enjoy the snarky tone of that book a little bit more than I did before, now that I understand better why Douglas Crockford is being snarky in the first place.Bottom line: I really wasn't expecting anything in particular from this book, and I wasn't even looking forward to reading it. I thought it would be just more words about JavaScript that would continue to make me hate JavaScript, but it changed my mind one page at a time. Before this book, reading about JavaScript would make me feel alternately bored or frustrated, like those who understood JavaScript and functional programming were part of some secret special club that I could not be a member of, but the tone and content of this book have now made me feel excited about the potential of what I can accomplish with this language going forward.

It is the most gentle and most practical introduction to functional programming that I have come across.I previously looked at the O'reilly book with a similar title but I found that the dependence on an external library(underscore.js) was practical but not instructive in getting my mind around the functional programming paradigm.The best chapter in my opinion is chapter 2. It lays a lot of the groundwork for 'functional thinking' and has the most efficient discussion of recursion as a programming paradigm. If you plan on skimming through the book, be sure to look at this chapter..The author also subtly reinforces functional thinking with well-placed phrases like: ".... maintaining a stack through iteration is not very functional".I think this book could have been written in Ruby and would still be as effective for establishing a functional mindset. However, the choice of Javascript as the vehicle of instruction is well timed because as most people know, Javascript is eating the world right now.

Excellent Javascript Book to Bring You to the Next Level By John Preston Cua I am currently running a “Javascript phase” where I read books or watch a lot of videos about Javascript as I have discovered that Javascript is a powerful and very useful language to learn and it is my language of choice, at the moment. If you know Javascript, you can do Web Development and Mobile Development using the same language. Within Web Development and/or Mobile Development using Javascript, you can use 2 different styles of programming to achieve your goal of creating/developing your final product: 1.) Functional Programming (which is in the title of this book) and 2.) Object Oriented Programming (which is actually part of the content of the book).This book for me is AWESOME as it delivers more than what you would expect from a book with a title of “Functional Programming in Javascript” as the author not only discusses and teaches how to program in a Functional Programming style using Javascript, but it also teaches how to use Javascript to program in a Object-Oriented style. Therefore no one style is neglected. This book, however, is still faithful to its Title as it goes in-depth in terms of learning Functional Programming using the Javascript language. It goes in-depth in Functional Programming by first introducing the different ‘moving parts’, ‘building blocks’ and ‘tools’ used for Functional Programming and then how to put everything together akin to understanding a machine by first dissecting it and understanding what each part does and then reassembling it to produce the final product again in order to further one’s understanding of the machine and its different parts.The book also talks about the pitfalls of Javascript and some more Advanced Topics within Javascript. The approach is highly practical and yet it does not forget to acknowledge the academic basis of Functional Programming in Mathematics. Therefore a section of the book was dedicated to briefly talk about Category Theory. A section I appreciate even though I don’t really know Category Theory. But at least the awareness of Functional Programming being born out of Mathematics was mentioned for suitable readers to appreciate.Other things you will learn from this book are Design Patterns and some recommendation of Libraries to use to help in Functional Programming so that you will not have to program these yourself.In short, this is a very good book to learn the strengths, weaknesses and different applications of Javascript.
