Advanced Scala and Functional Programming

Updated for Scala 3. This course is now fully compatible with both Scala 2 and Scala 3.

In this course, we will learn the tricks used by the top 1% of Scala developers. You'll write 2000+ lines of Scala code yourself, with guidance, and you will become a rockstar.

This course is for Scala programmers who need to design complex, scalable systems, or need to customize existing tools (e.g. Spark) or write their own.

Why mastering Scala:

it's the hottest language based on the Java Virtual Machine - the number of Scala jobs has exploded, but demand is even higher
Scala offers significantly higher pay (> 20%) than same-level Java positions - the top Scala devs are paid 2x, 10x, even more.
it's incredibly fun - once tasted Scala, you'll never want to get back
you will not have any trouble using some of the latest technologies written in Scala - Spark, Akka and more

I like to get to the point and get things done. This course

deconstructs advanced Scala concepts into the critical pieces you need
selects the most important ideas in Scala and separates them into the critical and nice-to-have
sequences ideas in a way that "clicks" and makes sense throughout the process of learning
applies everything in live code

The end benefits are still much greater:

a completely new level of skill with the Scala language
significant bump in salary when you switch to Scala - return on investment for this course >100x in the first year alone.
more enjoyable work - Scala is fun.
future-proof skills - you'll be able to work with some of the cutting edge technologies (Spark, Akka etc)

This course is for established programmers with experience with Scala and with functional programming at the level of the Rock the JVM Scala beginners course. I already assume a solid understanding of general programming fundamentals. If you've never coded before, this course is not for you.

The course is comprehensive, but you'll always see me get straight to the point. So make sure you have a good level of focus and commitment to become a badass programmer.

I believe both theory and practice are important. That's why you'll get lectures with code examples, real life Scala code demos and assignments, plus additional resources, instructions, exercises and solutions. At the end of the course, you'll have written thousands of lines of Scala.

I've seen that my students are most successful - and my best students work at Google-class companies and committing to Scala repositories - when they're guided, but not being told what to do. I have assignments waiting for you, where I offer my (opinionated) guidance but otherwise freedom to experiment and improve upon your Scala code.

Definitely not least, my students are most successful when they have fun along the way.

So join me in this course and let's rock the JVM.

Reviews summary

Scala and functional programming explained

Students say that this is one of the best Scala courses for intermediate learners. The course is particularly strong in explaining implicits and the Scala type system. Students gave positive remarks about the quality of the instructor, Daniel. They say that he explains concepts clearly and is engaging. One common suggestion from learners is to make the slides available and to include auto-pause when an instructor pauses. Overall, this course is well received by learners and is recommended for those with a basic understanding of Scala who want to advance their knowledge.

Great instructor.

"Daniel is a great (implicit: rocking) instructor."

Clear explanations.

"Having an intermediate level in Scala, I found this course very useful to understand the hardest concepts of this amazing language, notably the implicits and the type system."

Slides and Auto-Pause Needed

"The "takeaways" slides are available somewhere ?"

"It is possible to automatically pause the videos when the instructor wants to pause the videos?"
