Elixir’s straightforward syntax and this guided tour give you a clean, simple path to learn modern functional programming techniques. No previous functional programming experience required! This book walks you through the right concepts at the right pace, as you explore immutable values and explicit data transformation, functions, modules, recursive functions, pattern matching, high-order functions, polymorphism, and failure handling, all while avoiding side effects. Don’t board the Elixir train with an imperative mindset! To get the most out of functional languages, you need to think functionally. This book will get you there.
Functional programming offers useful techniques for building maintainable and scalable software that solves today’s difficult problems. The demand for software written in this way is increasing—you don’t want to miss out. In this book, you’ll not only learn Elixir and its features, you’ll also learn the mindset required to program functionally. Elixir’s clean syntax is excellent for exploring the critical skills of using functions and concurrency.
Start with the basic techniques of the functional way: working with immutable data, transforming data in discrete steps, and avoiding side effects. Next, take a deep look at values, expressions, functions, and modules. Then extend your programming with pattern matching and flow control with case, if, cond, and functions. Use recursive functions to create iterations. Work with data types such as lists, tuples, and maps. Improve code reusability and readability with Elixir’s most common high-order functions. Explore how to use lazy computation with streams, design your data, and take advantage of polymorphism with protocols. Combine functions and handle failures in a maintainable way using Elixir features and libraries.
Learn techniques that matter to make code that lives harmoniously with the language.

Yeah no problem! Thanks for the quick reply. I’ll keep my eye out for when it comes out

Hi Tom, we have a new coupon coming soon - can you hold off a few weeks?

Is the Discount still on? I get a message saying it is expired when I enter it at checkout

Just finished this book. It was a fantastic introduction to functional programming and the elixir syntax for an absolute beginner. If you have prior experience programming but not with functional programming then I’d still highly recommend this as a starting point.

You can start it directly, just do win+R and then type
cmd.exeand Enter.Higashimori
Okay, I ran cmd.exe in the Powershell terminal and that switched the terminal to cmd.
Trying ‘iex -S mix’ worked as intended after that. Thanks!
NobbZ
Good old
cmd.exe. Or LinuxHigashimori
What would you suggest in lieu of Powershell? I’m pretty new to all of this.
NobbZ
Please do not use Powershell, it has a built-in function
iex, which shadows theiexof elixir.Higashimori
Since the book’s forum is down, posting a question here.
I’m on the Dungeon Crawl app part, and I’m getting stuck near the beginning when I try to run iex -S mix. Page 111 of 160 in my version of the book, Creating the Character with Structs.
I receive this error in Visual Studio Code:
"PS D:\code\Functional_Programming_with_Elixir_Book\dungeon_crawl> iex -S MixInvoke-Expression : A parameter cannot be found that matches parameter name ‘S’.
At line:1 char:5
I’ve tried googling and that hasn’t yielded anything I’ve found helpful so far. Any help would be appreciated.
