The course that started Rock the JVM is still live..

Scala is one of the most powerful programming languages invented by humankind. This course taught 35000+ engineers, now working at the biggest companies in the world.

Although we have a completely revamped course specifically for Scala 3, This course will still be alive on Rock the JVM for as long as people continue to use the old Scala 2. It’s only fair - this course started Rock the JVM as a project.

This course is 100% compatible with the latest fully supported Scala 2 version (currently 2.13), and contains all the features of the Scala 3 version of the course:

Timeless Scala skills, on any version
Object Orientation
Functional Programming
Pattern Matching

and gives you the same perks:

Full code I write on camera (2000+ LOC)
Exclusive access our private Slack group
Takeaway slides
All updates free
Never expires

All the skills you need to be a productive Scala developer

After this course, you can contribute to codebases of medium complexity, which is about 80% of Scala code everywhere. You’ll be able to

understand idiomatic Scala code in any codebase
learn advanced Scala features faster with the right foundations
use Scala the way it’s meant to be, rather than an imperative Java with the Scala syntax

Specific Scala features you’ll master in this course:

Scala essential syntax
values, variables, types
expressions
recursion
String interpolation
object-oriented programming
classes, fields, methods
method notation and syntax sugars
objects and companions
object-oriented patterns simplified in Scala
collections
generics and the type system
functional programming
anonymous functions aka lambdas
higher-order functions
map, flatMap, filter - the primary functional programming primitives
mutability vs immuutability
for-comprehensions
pattern matching
loops and other parts of imperative programming (that we don’t use too much)

By the end of this course, we will write more code than a Scala beginner at their job in their first month. You’ll do that in 10 hours.

I'm a software engineer and the founder of Rock the JVM.

I'm a software engineer and the founder of Rock the JVM. I started the Rock the JVM project out of love for Scala and the technologies it powers - they are all amazing tools and I want to share as much of my experience with them as I can.

As of February 2024, I've taught Java, Scala, Kotlin and related tech (e.g. Cats, ZIO, Spark) to 100000+ students at various levels and I've held live training sessions for some of the best companies in the industry, including Adobe and Apple. I've also taught university students who now work at Google and Facebook (among others), I've held Hour of Code for 7-year-olds and I've taught more than 35000 kids to code.

I have a Master's Degree in Computer Science and I wrote my Bachelor and Master theses on Quantum Computation. Before starting to learn programming, I won medals at international Physics competitions.
