7 Free Scala Courses & Tutorials to learn Functional Programming
The following are my top free Scala courses and tutorials from Udemy, Coursera, and YouTube to help you learn functional programming.
Everyone knows the most powerful programming languages like Java, Python, C sharp, etc. However, they all come with specific issues that developers have gotten familiar with over time. For example, Java is one of the most powerful programming languages that allows you to build stunning applications from mobile to web development.
However, there’s one issue with Java. Java developers know that Java requires writing a lot of boilerplate code. Now you might say, it’s alright, we can write extra lines. Well, the more lines you write, the greater the likelihood of bugs. So, what’s the solution?
That is where Scala comes in. Scala is one of the most capable yet underrated programming languages, similar to Java. It requires less code, and you don’t have to write boiler code and worry about bugs. Its most impressive feature is that it runs on the JVM, sharing the same concept as Java. In addition, it provides functional styling.
Therefore, I have compiled this list of free Scala courses & tutorials for Java developers or anyone who wants to explore and learn Scala. Also, if you wish to invest in paid Scala tutorials, you can do that too.
List of Top Free Scala Tutorials

2. Functional Programming Principles in Scala — [Coursera]
The industry is becoming increasingly reliant on functional programming. Scala has become the main programming language for many applications, fueling this trend.
- Understand the principles of functional programming.
- Design immutable data structures.
- Integrate functional programming with objects and classes.
- Write purely functional programs, using recursion, pattern matching, and higher-order functions.
Scala combines both functional programming and object-oriented programming in a convenient package. As well as working seamlessly with Java, it also supports Javascript. Apache Spark, Kafka, and Akka are among the frameworks that use Scala as their implementation language. Sites like Twitter, Netflix, Zalando, and Coursera rely on it.
This course introduces the functional programming style and teaches you how to use it in your daily programming tasks, such as implementing business logic or modeling business domains. In addition, you will learn about proofs of invariants and how to trace execution symbolically.
Programming experience of at least one year is required. Ideally, you should have experience with Java or C#, but other languages such as C/C++, Python, Javascript, or Ruby will also suffice. It is recommended that you have some familiarity with the command line.

3. Scala at Light Speed — [Udemy]
Get an overview of what the Scala language can do with this free course from Rock the JVM. This course will help you become familiar with Scala’s foundations in just a few hours.
In this Scala tutorial, you will learn:
- Scala fundamentals
- Object-oriented principles in Scala
- Functional programming principles in Scala.
- Managing threads
- Foundations of implicit.
During this course, you will learn how to write essential code, think and approach problems, deal with threads, and use some “magical” structures that you won’t find anywhere else in the language. Additionally, you will make some analogies with existing programming languages to better understand how to write essential code, think and approach problems, and use threads.

4. Effective Programming in Scala — [Coursera]
This informative, hands-on course combines functional programming with object-oriented programming to help you improve your programming skills. Additionally, you will learn about the standard library and common code patterns.
In this Scala tutorial, you will:
- Use Scala idioms to model business domains and implement business logic.
- Develop a solid understanding of the language, allowing you to read and understand codebases written in Scala.
- Acquire best practices and standard patterns used in the real world.
- Work with asynchronous computations, handle failures, and manipulate recursive data structures comfortably.
This course teaches you how to use Scala to solve common programming challenges such as modeling business domains, simplifying complex problems, manipulating data, and running parallel programs.
Furthermore, you will learn how to handle errors, write tests, and leverage a productive development environment as you write high-quality code that scales to large applications.
