“Hello, Scala” PDF is now free

November 26, 2019: The PDF version of my book “Hello, Scala” is now free, and you can download it by clicking on the image below.

Future “updated and improved” versions of the book are being released as Scala Book. Currently an HTML version of the book is available here on the scala-lang.org website, and we’ll have PDF, MOBI, and ePub versions of that available once the creation process is automated and a few other issues are resolved.

But for now, click on the image below if you’d like to download the PDF of Hello, Scala for free:

Hello, Scala PDF

Hello, Scala (free preview)

Note: The print version of Hello, Scala on Amazon will be going up to $20 (USD) this Saturday, April 13, 2019. It’s currently just $10, so you know, buy it while it’s on sale and all that. :)

If you like free things, here’s a link to a free preview (PDF) of the new version of my book, “Hello, Scala.” The book is 257 pages long, and the free preview contains the first 120 pages of it, so I hope it’s a significant preview.

July, 2019 Update: Hello, Scala was previously available in PDF and Kindle versions, but hopefully there are some big changes coming, so those versions are no longer for sale.

Somewhere in mid-2017 I started working on a Kotlin programming book, but then I had to get away from it to work on other things. When I got back to it recently I looked around and felt like the world didn’t need another “Introduction to Kotlin” book — there are a couple of good ones out there, including Kotlin in Action, and the kotlinlang.org documentation is excellent — so I decided to ditch the project completely.

Kotlin Quick Reference

But then when I started writing some Kotlin code again I realized that what I really needed was a quick reference. I didn’t want to have to dig through a tutorial book or website to find what I need, I just wanted something like a large cheat sheet where I could quickly find the Kotlin syntax and examples for whatever I was working on at that moment. So I decided to strip down what I had already written and create both a book and a Kotlin Quick Reference website.

I just released a large-font version of the Functional Programming, Simplified PDF. My hope is that it will help those people who want to read it in a Kindle reader. If you’ve bought the PDF, you can find the new file in your Gumroad.com account.

Hello, Scala book (an introduction to Scala book)

July, 2019: Hello, Scala, is now available only in print form:

It was previously available in PDF and Kindle format, but there are some big changes planned, so those versions have been removed for the time being.

As the subtitle of the book shows, the purpose of this book is to help you learn the Scala programming language with small, easy lessons. The book consists of a little over 50 lessons, and it’s 258 pages long.
