Everything should be made as simple as possible, but no simpler.

Learning Scala - My Insights

It passed almost 5 months since I have been learning Scala programming language. This learning is a part of bigger path which I decided to go through to be more familiar with current trends in big data, machine learning and cloud computing.

When I decided to start learning scala the first question coming into my mind was how to start ?

Because I am rather a fun of books, I bought one - “Programming Scala: Scalability = Functional Programming + Objects” by Dean Wampler and Alex Payne” and started reading…. but this was not a good idea. The book I have chosen was written in not an easy going style and I think was too hard for the beginning. After few hundreds of pages I felt lost. At the same time on coursera ‘Functional Programming Principles in Scala’ course was reactivated. Not thinking too much I signed in and started participating. After few weeks I earn a certificate of accomplishment but this was not an end of my journey. I started participating in another course “Functional Program Design in Scala” from the same author (Martin Odersky) as the previous one. In parallel I have started reading a book “Programming in Scala Second Edition” by Martin Odersky, Lex Spoon, Bill Venners and I found it very helpful. Currently (in the time of writing this post) I have done “Parallel programming” course and already enrolled for a “Big Data Analysis with Scala and Spark” (still waiting for course publishing)

I think the knowledge I acquired, thanks to those courses and book, is sufficient to start writing and reading programs in scala. Of course it takes some time to be as proficient as in java but I am little closer to this target each day.


The aim of this section is to gather the valuable resources regarding scala.

Online courses


Cheat sheets




First steps

My recommendation about ordering of going through the resources for beginners:

  1. Functional Programming Principles in Scala
  2. Programming in Scala by Martin Odersky, Lex Spoon, Bill Venners
  3. Functional Program Design in Scala
  4. Parallel programming
