Community feedback and help

There are many active users who offer advice on Scala style and functional programming. See More

Top Con

Not a good starting place for beginners

It's best to have at least a basic understanding of programming before tackling the exercises on exercism.io. You also have to know how to set up your development environment, as you will be coding everything locally (versus websites that provide you an editor right in the browser). See More

Top Pro

Encourages Test-Driven Development practices

With tests already implemented, you can focus on learning the language quickly with a tight feedback loop for verifying your code works. See More

Top Con

Custom commandline client

Exercism requires using a CLI utility to fetch and submit exercises. This is inconvenient compared to web-only alternatives, and poses an additional barrier to entry for some users. See More

Top Pro

Practice with production tools

Unlike many code practice websites, Exercism requires the user to develop and test entirely offline, submitting only the finished code. This promotes familiarity with essential tools and workflow, not just the bare language. See More

Top Pro

Human review and feedback

Rather than merely test for code correctness, Exercism uses peer review to improve general programming techniques. Users are encouraged to comment on others' solutions, and refine their own based on feedback. See More

Programming in Scala: A Comprehensive Step-by-Step Guide, 2nd Edition

Top Pro

Written by the creator of Scala

"Programming in Scala: A Comprehensive Step-by-Step Guide" is written by Martin Odersky, the creator of Scala. See More

Scala for the Impatient

Top Pro

Focuses on teaching the language

Many Scala books aim to teach not just the language, but programming theory as well. "Scala for the Impatient" focuses only on teaching the syntax and features of Scala, making it a great option for experienced programmers looking to pick up the language quickly. See More

Top Con

Author takes a Java-centric approach to many topics

If you aren't arriving at Scala with a Java background, some of the examples may seem unnecessarily focused on OOP inheritance relationships and core Java libraries. See More

Top Pro

Easy to read and concise introduction to Scala

For experienced developers, this book will quickly get you running with Scala. See More

Top Con

Unreadable source code on Kindle

In order to view a properly formatted version of the code, the reader has to click a link which takes them to the index. It is then extremely difficult for the reader to find their original place in the book and continue reading. See More

Functional Programming in Scala

Top Con

Not for beginners

The material gets advanced pretty quickly. The material in the book is more effective if you already have an introduction to category theory and combinatorial analysis. See More

Top Pro

Creative, fun exercises

"Functional Programming in Scala" offers no shortage of exercises. Throughout the book, exercises and examples are plentiful to help the reader put what they're learning into practice for a better understanding. See More

Top Con

Only uses Scala as a medium to teach functional programming

Rather than focusing on teaching the language (such as the syntax), "Functional Programming in Scala" only uses Scala as the medium for teaching functional programming. This means the reader needs to already have some experience with Scala. See More

Top Pro

Does an excellent job of teaching functional programming

"Functional Programming in Scala" focuses on building a strong foundation in Functional Programming(FP). It fully explains FP concepts, including the "why" behind everything discussed. See More
