Top 5 Scala Books for Beginners in 2021
Scala is a popular programming language that combines object-oriented and functional programming into one concise language. It was created by Martin Odersky in 2004. Scala is compiled to run on the Java Virtual Machine (JVM) and is compatible with existing Java programs.
In this post, we will look at the five best Scala books for novice programmers to help them get mastery over Scala programming.
Why Learn Scala
Here are some reasons why you should start learning Scala:
Simple Syntax: Scala has a simple syntax for defining functions and it allows functions to be nested easily.
Java Compatible: Scala is compatible with Java. It also supports new technologies like Data Science or Blockchain with its amazing tools.
Popular: Tech giants like Twitter are using Scala within production because it works!
Community: Scala is good for self-learners due to its open and growing community.
Professional Development: Finally, your value will be bigger if you know the Scala programming language well.

More Ways to Learn
The world of Scala programming is in constant growth and the learning opportunities are simply endless!
While learning, I always recommend doubling up on resources so that you do not burn out on just reading. Using all of the senses and changing your environment is the best way to learn a lot in a short amount of time.
Here are some more ways you can learn:
Udemy: I recommend taking Udemy’s course Scala & Functional Programming for Beginners, which is a highly-rated bestseller that is packed with 15 hours of video content.
Coursera: Coursera offers Functional Programming in Scala Specialization, which is a highly-rated series of courses that you can take altogether or separately. The course is project driven and gets you coding.
And there’s one last things: I’ve compiled over 70 free learning resources for beginner programmers to help you continue your journey. I hope to see you over there and have a wonderful day. 😊
